Deemed impregnable by both the Germans and the Allies, it was incapacited within half an hour following a bold attack on May 10, 1940 by a German elite force using glider planes. Thirty hours later, Eben-Emael surrendered.
The current fortress is exploited by volunteers, some ex-military, that spend every effort to keep the fortress alive. Guides lead you through the 5 km of tunnels during a tour of 2-3 hours (depending on how much questions you ask, or how many stories they tell).
This visit is an absolute must, but carefully check the limited opening times to avoid disappointment.
ID 427 on the Belgian tourist map. In the vicinity is the Eben-Ezer tower. a curiosity well worth visiting.
