Libeňský plynojem Water structure
The Libeňský plynojem, commonly known as 'Koule', is a distinctive technical structure located in the Prague district of Libeň. Built in 1932 by Vítkovické hutní těžařství and equipped by Českomoravská Kolben-Daněk for Pražská obecní plynárna, it originally served as a pressure gas holder to meet the growing industrial demands of Libně, Karlín, Holešovice, and Vysočany. After being damaged during World War II, it was repurposed in 1949 by the Výzkumné a zkušební letecké ústavu as an underpressure reservoir for aerodynamic testing at high speeds (up to Mach 3.5). Today, it stands as a unique experimental facility for aerodynamics and fluid dynamics research.
Constructed in response to early 20th-century Czechoslovakia's rapid industrial growth, the Libeňský plynojem was built by Vítkovické hutní těžařství and equipped by Českomoravská Kolben-Daněk for Pražská obecní plynárna. It addressed increasing industrial demands in areas such as Libně, Karlín, Holešovice, and Vysočany. The project was led by Tomáš Keclík, a stavební inženýr based in Prague.
Architecturally notable for its innovative design, the Libeňský plynojem is one of the first pressure gas holders in Czech lands during the 1930s. It features a spherical shape with a twenty-meter diameter and stands on eight two-layered sheet metal legs set into concrete foundations. Constructed from 14 mm thick sheets joined by multi-row riveting, it was originally designed to hold significant volumes of pressurized gas. After World War II, the structure underwent modernization to serve as an underpressure reservoir for aerodynamic testing.
Ownership and administration have changed over time. Initially built in 1932 by Vítkovické hutní těžařství, it was repurposed in 1949 by the Výzkumné a zkušební letecké ústavu for aerodynamic testing purposes. This marked a shift from its original function as a gas holder to becoming an essential component of Czechoslovakia's research infrastructure.
Several key events have shaped its history. Constructed in 1932, it served as a pressure gas holder until World War II when it was damaged during the May Uprising of 1945 due to shrapnel from projectiles. In 1949, following repair and repurposing by Výzkumné a zkušební letecké ústavu, it began serving as an underpressure reservoir for aerodynamic testing. The structure has also been the subject of artistic interest, featuring in works by members of Skupina 42 and being mentioned in literary pieces by Bohumil Hrabal and Arnošt Lustig.
Today, the Libeňský plynojem is situated on a hill above the Palmovka intersection near Libeň. Although it no longer stands out due to surrounding urban development and vegetation, its historical significance remains intact. The site is accessible with permission from VZLÚ a.s., offering visitors a glimpse into both its industrial past and current role in aerodynamic research. Its unique history and transformation make it an intriguing destination for those interested in technological evolution and cultural heritage.
The Libeňský plynojem, or 'Koule', is more than just a technical structure; it embodies the dynamic interplay between industry, war, and scientific advancement. As both a historical artifact and a modern research facility, it offers a unique perspective on Czechoslovakia's technological journey. Visitors are invited to explore this remarkable site, where history and innovation converge in a single location.
