Butzweilerhof, Historic airport complex in Ossendorf, Germany.
Butzweilerhof is an airport complex in Ossendorf featuring buildings from the 1930s that blend modernist design with aviation needs. The main building displays symmetrical window rows, white plastered facades, and a striking basalt eagle relief above its entrance, while hangars, a control tower, and administrative spaces complete the site.
The site was built in 1912 as an imperial flight school and military airfield, becoming Germany's second most important aviation center after Berlin-Tempelhof during the 1930s. Civilian operations ended in 1957 when Cologne-Bonn Airport opened.
The site reflects New Objectivity design principles, where modernist forms merge with practical purposes through its tower, hangars, and office spaces. Visitors can see how function shaped every architectural choice here.
The complex is now open for visits and houses businesses and offices in its restored buildings. The grounds are best explored on foot, allowing time to see the different structures and outdoor areas.
The site is one of only two complete 1930s airport complexes remaining in Germany, with original concrete runways and restored worker housing still visible. This rare combination of intact aviation infrastructure and residential buildings offers a window into early aviation history that few places can match.
