View inside of the main hangar of the Rozas Aerodrome (LERO), in Castro de Rei, province of Lugo, Galicia (NW of Spain)

Build by the Germans during the WWII, it still keeps one of the three original hangars (the other two were dismantled and translated to Palma de Mallorca and to the Airbase of Cuatro Vientos, Madrid, in the late 1950s).

In 1949 it became the central airport of Galicia, while the Santiago de Compostela Airport was being build.
