Armádní muzeum U Trigonometru

Bunkr Milostovice (Pěchotní srub OP-S 25 "U Trigonometru") is one of the best-equipped bunkers in the Czech Republic, a 1938 Czechoslovak fortification now serving as a museum. The interior has been restored close to the ideal state intended for 1938, and the object is fully armed — notably the first in the history of Czechoslovak fortification museums to install two L1 fortress cannons in the firing chambers. Declared a cultural monument in 2009, it is part of a unique section of fortifications.
