Register to join ISAP for an exploration of the old NATO Caves in Maastricht on the 27th September at 10:00am.

 

NATO used the quarry as a war and exercise headquarters, and the complex had been under the Official Secrets Act since 1956. The complex was an important communications center for NATO!

 

Please bring warm clothes and closed shoes, since it's only 11°C inside the caves.

 

See you there!
