The Swiss House

In the corner where Unter den Linden meets Friedrichstraße, there is a house with more than 85 years of history in Berlin. Today, this building stands as one of the original places of the city and a survivor of the Allied bombing campaign and the Luftangriffe of the Second World War. 

[Unter den Linden Nr 22 Ecke Friedrichstraße nr 155-156 during the days of the Third Reich. At left corner can be seen the “Haus der Schweiz”. At right, the famous Viktoria Hotel and Café, 1939-40. Note Friedrichstr. Bhf in the background.]

The house was built during 1934-1936 by Swiss architect Ernst Meier-Appenzell with a clean façade, an arcade and rectangular windows, in a monumental building style. The client was the “Haus der Schweiz GmbH”, to which the Swiss bank Leu, the Swiss bank and the Swiss Federal Railways had joined forces. Like many Swiss companies, they had considerable sums of German Reichsmark.

Since these were classified by the Nazis as “Sperrmark”, however, a transfer of the money into Switzerland would have been associated with considerable price losses. Instead, the three companies bought a plot of land on the corner of Friedrichstraße/ Unter den Linden and had a six-storey business and office building built there - “at the first business location of the Reich capital”. The property was intended as a financial investment, but served at the same time also quite representative purposes.

The building had the lettering Haus der Schweiz, prominently displayed on both sides of the façade, as well as a Wilhelm Tell figure. The bronze sculpture, however, is not William Tell, but his son Walther. Supposedly a trick of the builder: because the Nazis did not want to tolerate a representation of the freedom fighter and Swiss national hero himself, they trained just now his son with a crossbow and an apple. On the other hand, the Nazis could not say anything - and the Swiss national pride was still respected. In the spring of 1936, the builders themselves became the first tenants to enter the ”Haus der Schweiz”.

In the shops on the ground floor, the Swiss Tourist Office opened a branch (Schweizer Verkehrsbüro), where citizens could book train journeys to Switzerland. 

During the war, this zone was severely damaged by Allied bombings, the building was hit on the evening of 9/10 April 1941 during the raid made by RAF British bombers which affected many areas in Mitte including the famous Staatsoper den Linden. Some bombs hit this area on 3 February 1945 during the massive US air strike on Berlin, with serious damage to adjacent buildings including the famous Hotel Viktoria next to the Swiss House.

Years later, the Soviet offensive in the city inflicted more damage, but thanks to the modern construction method, this building survived the bombing of Berlin at the end of war as the only one in the area relatively intact.

The employees of the Swiss companies, which until 1945 had had their headquarters in the house, had largely fled in the turmoil of the last years of the war from Berlin, but the house remained the property of the “House of Switzerland GmbH”.

When Berlin was divided by two, while the DDR government expropriated the owners of many surrounding buildings, the “Swiss house (…) was administered by the Berlin state housing administration (…) as a foreign property”, as can be seen from a 1952 official note. Apparently, the DDR government did not want to mess with Swiss banks. Nevertheless, they used the house for their own purposes. Among others, the Ostberliner Sparkasse, the German Foreign Trade Bank and a HO food market moved into the shops. The upper floors were rebuilt in the early 1950s for the “Coordination and Control Center for Agriculture, Forestry and Water Management”.

The Whitley

The Armstrong Whitworth Whitley was one of the three ‘strategic’ bombers types with which Britain went to war in September 1939. The Whitley was conceived as a night ‘heavy’ bomber and was RAF’s first monoplane bomber and the first one to penetrate on Germany airspace. 

With a crew of five men, and powered by two Rolls-Royce Merlin X engines, the Whitley was capable of 230 mph (370 km/h) at 16,400 ft (5,000 m) and was bombed with up to 7,000 lb (3,175 kg) of bombs in the fuselage and 14 individual cells in the wings.

Following the outbreak of war in September 1939, the Whitley participated in the first RAF bombing raid upon Reich territory and remained an integral part of the early British bomber offensive until the introduction of four-engined RAF bombers namely the Short Stirling or the Lancaster. Already an outclassed design when the war started, in 1942 it was retired from first-line bombing sorties. This two-engine bomber equipped Bomber Command’s 10, 51, 58, 78 and 102 Squadrons, all from No 4 Group.

It participated, along with Hampdens and Wellingtons in the first British-attack over Berlin on the night of 25 August 1940. And during the next 6 months, the Whitleys would be on first line delivering bombs by night to the Reich capital.

With 1,814 Whitleys built, they flew a total of 8,996 operations with Bomber Command, with 9,845 tons of bombs dropped and 269 of them were lost in action.

Ivan kommt

Berlin was also bombed by the Soviets, years before the final Red assault over the city in 1945.

Hitler invaded the Soviet Union on 22 June 1941, the largest offensive in History at the time, and German forces quickly advanced throught the vast steppe towards Moscow, the main target. As soon as 19 July, Hitler had issued his ‘War Directive No 33’, decreting the attack of Moscow by bombers of Luftflotte 2 in reprisal for the raids on Bucharest and Helsinki. 

But “Klara Zetkin” —the Luftwaffe’s codename for Moscow- was heavily defended and the bombings were poor. After the Nazi attack of the capital on July 21/22, 1941, when the Germans dropped a total of 104 tonnes of HE bombs and 46,000 incendiaries for over 5 hours, Stalin ordered immediate retaliation against the Reich capital.

On the evening of 7 August 1941, 15 Ilyushin DB-3T torpedo bombers of the Baltic Fleet operating from an island airstrip off the Estonian coast struck Berlin after travelling a distance of more than 600 miles (1,000 km). All returned safely. While the damage caused by the twin-engined bombers was negligible (each carried fewer than 1,000 pounds of bombs), the Kremlin propaganda machine was quick to trumpet the success of the raids.

[Photo: Century of flight.]

Later, at dusk on 10 August 1941, a formation of VVS (Voyenno-Vozdushny Sili, or Red Air Force) Yermolayev Yer-2 medium bombers and 14 of Stalin’s prized four-engine Petliakov Pe-8 formed up over Pushkino Airfield in Leningrad for the raid on Berlin. The planes were to be joined over the city by two full squadrons of Ilyushin Il-4 bombers flying from Estonia. Unfortunately for the Soviets, the mission was cursed with misfortune from the start, several Pe-8s had to abort due to engine problems and one of the heavily loaded Pe-8 crashed immediately upon take off. The bombing was a total disaster. More attacks followed, with minor damage.

[The big size Pe-8 four engined was the only strategic bomber built by the Soviets during the war, but the unreliability of her engines and low numbers built (93) made the bomber a failure in action.]


By late 1941, the Wehrmacht was so close to Moscow that Stalin was forced to forget strategic bombing, apart from a 100-bombers raid on 29 August 1942 (minor damage), until 1945.

Naval DB-3s flew a total of 10 sorties over Berlin before their base at Saaremaa had to be evacuated in the face of imminent German capture. The final attack was made on the night of September 4-5. A total of 86 naval aircraft participated in the raids, of which 33 were reported to have reached Berlin, while others bombed secondary targets, including Stettin, Königsberg, Danzig, Swinemünde and Libau. Daylight bombing was even tried, but met with no success and was cancelled.

The Soviet bomb ton dropped over Berlin is less than 1% of the total for the Allies during Second World War.

At night, Berlin first system defence was based mainly in the use of anti-aircraft searchlights (Flakscheinwerfer). Hundreds of them were positioned around- and in the city, and their task were to find and track enemy bombers, showing them to the anti-aircraft batteries at night.

[Here, members of the Hitlerjugend (Hitler Youth) served as crew of one during their duty with Luftwaffenhelfer in Berlin Tiergarten in 1943. Literally “air force assistants”, the Luftwaffenhelfer service was posted from January 1943 to aid in the Defence of the Reich. The order called for drafting school classes with male students born in 1926 and 1927 into a military corp, organised by Hitlerjugend and Luftwaffe staff.

They were know as the “Flakhelfer-Generation”. Their average age when they were called up was sixteen and a total of about 200,000 served during the war, including females from Bund Deutscher Mädel (BDM).]

[Photo: Bundesarchiv.]

The searchlights were based around extremely high-powered Carbon Arc lamps, and the German iused three types divided by the size and diameter parabolic glass reflector: 60 Centimetre, 150 Centimetre and 200 Centimetre.

In September 1940, Germany had 2,540 searchlights (60 cm and 150 cm). During the war, this number grew rapidly — by February 1944,  this figure has raised to 13,748 searchlights.

[A British four-engined bomber (most probably a Lancaster) caught at night during an air raid over the objective, as viewed from an above fellow bomber.]

The silhouette of the bomber is clearly evident as German searchlights raised their light against the clouds and overcast, showing the sky as a bright screen. The white traces are a mix of searchlights and British target indicators (TI), flares dropped by the bombers to mark and illuminate the target.

This photo was taken over Hamburg, on the night of 24/25 July 1943 during the infamous “Operation Gomorrah”. That summer night, the RAF Bomber Command created a perfect “fire storm” that engulfed the city and more than 50,000 civilians were killed.

The Flying Suitcase

One of the three bombers types beside Wellingtons and Whitleys which participated on the first British attack over Berlin in August 1940 was the Handley-Page Hampden, model HP 52. 

[A two-ship formation of Handley P Hampdens from No 44 Squadron RAF over England.]

[Photo: LIFE images.]

That first night over Berlin, 46 Hampdens bombers from Nos 49, 50, 61 and 144 Squadrons were sent to attack the ‘Big City’. Of these six were lost, five through fuel shortage and one missing believed also to be from the same cause. Two of these losses were from 50 Squadron. The last raid a Hampden was dispatched to bomb the Nazi capital was on 21 September 1941. Over the period of thirteen months 20 Hampden raids were made averaging twenty six aircraft per raid. The largest concentration involved fifty aircraft and the smallest ten. During the period 34 aircraft were lost of which 23 (58%) were due either certainly or probably to fuel shortage. By contrast only seven were attributed to enemy action. 50 Squadron lost nine aircraft, of which seven were out of fuel, one shot down by enemy action and one through a forced landing due to engine problems. There were six fatal casualties and two POW’s. On a trip to Berlin a Hampden’s bomb load would equate to four 500-lb bombs plus some incendiaries. Its endurance with this load was just over ten hours.

At the outbrak of war, Bomber Command was equipped with 6 operational squadrons of Hampdens under No 5 Group. The Hampden made its combat debut on 3 September 1939 searching German ships off the coast of Heligoland. It was a twin-engined medium bomber, with a crew of four and a max speed of 247 mph (397 km/h) at 13,800 ft (4,210 m); the bombload was of 4,000 lb (1,814 kg) bombs. The newest of the three RAF bombers, the Hampden, was often referred to by aircrews as the ‘Flying Suitcase’  because of its cramped crew conditions.

The RAF took a total of 1,432 Hampdens, the last of which was delivered in March 1942. The bomber ceased operational service in October 1943, but was retired from frontline raids over Germany a yerar before due to the increasing power of Third Reich defences. Almost half of the Hampdens built, 714, were lost on RAF Bomber Command operations, with 1,077 crew killed and 739 reported as missing. German Flak accounted for 108, 263 Hampdens crashed because of “a variety of causes” and 214 others were classed as “missing”.

The defences – Air detection (III)

The Freya systems of the German early warning radars were highly successful, but they need another set to help in targeting air objectives.

Anti-aircraft targeting radars, or FuMG (from Funkmeßgerät, or radar) were not in service when the war broke out. From 1939, GEMA and Telefunken starting to develop more accurate radars with a more concentrated beam to firing accuracy of the heavy anti-aircraft artillery’s guns.

This radar, called the Würzburg FuMG 39 operated on 50 cm wave length and had a range of 25 km with a range accuracy of 25 m. A rotating dipole antenna and a pulsed radar was used. The rangefinder was provided with a cathode-ray tube screen (CRT). The distance and ranging data would be provided to a command and control system at a Flak battery. Twenty of these units were delivered by 1940 to the Ruhr area. By the end of the war, over 4,000 units of this and upgraded models (Würzburg D) had been deployed in Europe, making it the standard radar system with the Luftwaffe. They were manned by a crew of six. 

[These photographs show a Würzburg FuMG 39/62 model T, seen with its wooden traverse plate.

In 1941, Telefunken followed up on their successful Würzburg system with a larger, more sophisticated set fittingly known as FuMG 65 Würzburg-Riese (“Giant”). Making use of the same conical-scanning system, the Riese was a much larger system with a 7.4 meter antenna and much more powerful transmitter that gave it a range of up to 70 degrees. Combined with the added accuracy afforded by the conical scanning system, the Würzburg-Riese provided the Luftwaffe with a long-range system capable of providing accurate enough information for gun-laying. with a range of about 60 km. This type began to enter service in 1941, and over the course of the war roughly 1,500 would be built.

Several types and improvements were developed by Germany during the war, increasing range and facing British radio countermeasures, being the Jagdschloß radar antenna-array the other great advanced unit. This system, called FuG 404, became operational in 1944 and it was very difficult to jam. Just 80 of them were built. With a detection range of 300-400 km, long range warning devices like this or the FuMG 41/42 Mammut radar unit (six or eight Freya switched together) detected enemy formations assembling over the North Sea prior move towards the Reich, alerting German defences for incoming air raids.

All German systems and radars were highly jammed by the British countermeasures chaff from the summer of 1943, named “Window” (known as ‘Duppel’ by the Germans), metal strips with aluminium foil. This obliged the Germans to improve their early warning system -the Kammhuber Line- and radar AI devices (airborne radar) with new frequencies and create new night fighting tactics.

    The defences – Air detection (II)

    RADAR was the acronym for Radio Detection And Ranging, with the first sets being tested by British and Germans at the same time during the early years of the 1900s.

    Its combat debut was during Second World War. It was an invaluable air detection aid whenever bad weather, darkness or the enemy’s action made impossible to track and locate an incoming raid. During the next years, RAF and Luftwaffe will play “cat and mouse” in radar procedures in the ensuing Bombenkrieg.

    [This picture shows the GEMA complex and buildings, where the German radar was developed located at Berlin. In 1940, more than 6,000 people worked here.]


    The birthplace for the German radar was GEMA company (Gesellschaft für elektroakustiche und mechanische Apparate - “Association for Electroacoustic and Mechanical Equipment”), founded by Paul-Günther Erbslöh (1905–2002) and Hans-Karl von Willisen (1906–1966). They worked together and after left Telefunken, developed the first air warning radar system.

    The installation was overrun by the Soviets in May 1945. Most of the equipment and many of the people were deported to Russia as part of the war bounty. 

    The first radar unit developed by GEMA in 1937 was the FuMG 403 Panoramagerät Stützpunkt (Plan Position Indicator-PPI) display radar, built in 1941 at Tremmen near Berlin (40 km west of the city) at a cost of 500,000 Reich Marks (RM). The 20 m large antenna is located in the top of the concrete tower and it rotates through 360 deg. at 6 rpm. Range is 120-300 km. The radar display station is located in the base of the tower and a PPI display. The tower was linked by landline to the headquarters of the 1st Flak Division in the Zoo’s Turm. The site was blown up after the war by the Russians.

    From the early works on Panorama, GEMA created an advanced and more compact unit, and this would be the start of the radar net of the German defences.

    Named after the Norse Goddess Freyja, the Freya FuMG 450 was the first operational early warning radar defence system. Before the beginning of WWII, in 1938, just eight of these units had been delivered by GEMA and deployed along the German border manned by the Luftwaffe.
    The early versions had a range of 60-80 km which was later increased to 120 km. Azimuth accuracy was 1.5 degrees and better. Developed from a Kriegsmarine (Germany’s war navy) radar, its lower frequency range (120-166 MHz vs 368 MHz), longer wavelength (2.5 m vs 50 cm), and longer range. It was more advanced than the British system, but more complex what it means that it was not totally readied and needs improvement when the first raids came.

    Freya was first successfully used on December 18, 1939 when two stations detected an approaching daytime raid on Wilhelmshaven by 22 RAF Wellington bombers at a range of 113 km and guided fighter planes toward them via radio, downing half of the enemy’s force. This early success of radar left the Luftwaffe so impressed that Freya network was the chosen one to guard Germany’s western border.

    Anyway, these radars were only able to spot and track incoming aircraft, not to determine the exact range and height.

    The defences – Air detection (I)

    The Nazis developed a complex net to defend the Reich and occupied Europe from air raids. This superb detection net goes from observation of incoming attacks to the latest and more sophisticated elements of electronic radar and radio to track enemy planes and to assist the AA (anti-aircraft) guns in their role against the Allied ‘Terror-bombers’.

    At the beginning of the war, German air detection was based on primary methods and systems like the observation sites.

    After plotting enemy aircraft the site will pass this essential information to the defence and fighter direction centres to defend the Reich territories. This method was highly successful during the Battle of Britain in the summer of 1940 employed by the British Royal Observer Corps (ROC). At night, it had obviously no usefulness.

    The air-defence instruments also consisted of sound location equipment. The Germans used a complex system, called Horchgerät, during early stages of the war, and revitalized during the Summer and Fall 1943 after their radar defence net failed as a consequence of the introduction of the first electronic countermeasures like ‘Window’ (ERC & ECM) by the British.

    The system idea was to hear the sound of the engines of the incoming aircraft and track their height, warning the defences of an incoming enemy raid. For typical aircraft speeds of that time, sound location only gave a few minutes of warning.

    It consists of four acoustic horns, a horizontal pair and a vertical pair, connected by rubber tubes
    to stethoscope type earphones worn by the two technicians left and right. The stereo earphones enabled one technician to determine the direction and the other the elevation of the aircraft.

    Berlin Wintergarten (Part II)

    In the end, Berlin’s WinterGarten collapsed under the carpet of bombs dropped by the Allies during the last year of the war.

    Already damaged during the 1943-44 British bombing campaign, the theatre was destroyed on 21 June 1944 during an American raid; that day 606 US heavy bombers dropped their bombs over the German capital. Finally, it took a heavy toll again during the large US attacks of February and March, 1945.

    Berlin Wintergarten (Part I)

    The Berlin Wintergarten theatre was a large variety theatre (“Varieté-Bühne”) placed in Friedrichstraße Ecke Dorotheenstraße.

    Owned by Hermann Gebers, it opened in 1887 as a recreational center of the Berlin Central Hotel, but also as a venue for concerts and theatrical performances. The Skladanowsky brothers showcased the first short movie presentation ever at the theatre in 1895, making it the first movie theater in history. But it was a multi-use variety theatre, not a true kino (‘cinema’).

    Against a background of inflation and depression, Berlin drew the talent and energies of the rest of Germany towards its glittering cabaret performances and burgeoning sex tourism industry.

    Berlin’s interwar reputation of hedonistic decadence and debauchery is familiar, but the Weimar Republic (1918-1933) privileged an outpouring of cultural creativity in the Bauhaus movement of modern art and the development of the ‘International Style’ in modern architecture too. The rise of the Nazis to power and government stop all of this and make the city back to the 1900s.
