Fort Aalsmeer houses the CRASH Luchtoorlog en Verzetmuseum (Aerial Warfare and Resistance Museum) ’40-’45. The museum relates stories of airplanes that crashed during World War II.
Wreckage that was recovered by CRASH or the Dutch Royal Air Force makes the fate of the aircraft crews visible and tangible. Their tales are brought to life by photos and personal objects.
CRASH also includes an impressive section on the resistance in the municipalities of Haarlemmermeer and Nieuwkoop. In addition, a space in the fort has been used to recreate an English control tower with radio room as it would have looked like during World War II. Another museum hall houses the complete Spitfire fighter plane that is part of the CRASH collection.
