Remarkable event in VZLU´s history – Palmovka gasholder has become a cultural monument

The gasholder in Prague – Palmovka was declared a cultural monument by the National Memorial Office in 2006 under the name the Former Gas-Holder of Prague District Gasworks in Prague 8 Libeň.

Built in 1932, the Libeň gasholder served its original purpose for 10 years only. At the end of World War II it was hit by shots fired from an aiplane´s gun, which prevented it from being used further on. In 1949 it was handed over to VZLU, which made it a high speed wind tunnel, the biggest facility of this kind ever built on the territory of former Czechoslovakia.

The high speed aerodynamics wind tunnel is a unique experimental facility used for aerodynamic calculations and tests at high flow speeds up to M3.5. In September 2007 the gasholder was open to the public for the first time on the occasion of the Day of European Cultural Heritage (more than 800 visitors).
