Festungswerk Hondrich - KP Heinrich

Kommandoposten Heinrich (A1956) is a Swiss fortress and museum at Hondrichhügel near Spiez on Lake Thun, built into the rock between 1941 and 1943 and only declassified in 2005. The volunteer-run association presents the history of the command post, observation positions and Swiss artillery doctrine, with regular Tuesday-evening guided tours for individuals.
