Photo Gallery Final Call for Airlift Airport

Tempelhof airport is slated to close this year, but some Berliners are launching an effort to save it. A citywide voter referendum on April 27 could decide its fate.

Some of the airlines that still use the airport fought to keep it open in court, but their case was rejected last year. Tempelhof is slated to close this year. Advocates who want to keep it open say the constant threat of closure explains the amount of vacant space in the enormous building.

The airport is notable both for its role in the Berlin Airlift and as an example of Hitler's architectural ambitions. There are still a few remnants of the grandiose plans for Hitler's favorite airport. The present building, designed by the architect Ernst Sagebiel, was to impress visitors to Germania, the planned capital of the victorious Reich.

The terminal's original entrance hall was three stories high. In the 1960s a floor was put in to bring it down to a more human scale. But it is possible to visit the imposing hall upstairs. This hall is only half of the height of the original.

Much of the original plaster was taken away by the US military to help restore other parts of the building after they took it over in July 1945. The airport is now a protected monument.

Tempelhof is designed as a semi-oval with 14 towers. The roof was originally intended to be used as a viewing platform for the audience at big Nazi events, such as Hitler's birthday. The airport was only completed during World War II and was used as a giant aircraft factory.

The airfield's history and its significance predates even Nazi rule. This 1928 picture shows Lufthansa transit buses ferrying passengers from the airport into the city center, six kilometers to the north.

The airport terminal opened in 1923, but had been used for aviation since 1903. In August 1909 the first Zeppelin landed in the capital. This photo was taken in 1928.

Tempelhof has about 300,000 passengers a year on around 40,000 flights -- that's compared to the new Berlin Brandenburg International Airport (BBI), built to handle 20-25 million passengers.

Tempelhof was the gateway for many famous visitors to Berlin. Former US President Ronald Reagan arrived at the airport on June 11, 1982.

Tempelhof airport is set to close in the name of moving all traffic to BBI, but some argue a city airport is invaluable. The matter will be put to a citywide referendum on April 27.
