Former Nazi defenses now home to thousands of bats
Western Poland’s long forgotten Ostwall fortification serves as both a WWII museum and a refuge for flying mammals

An awe-inspiring Nazi defense line in western Poland has taken on a new role in peacetime as home to tens of thousands of bats in what is Europe’s largest artificial roost.
The 37,000 winged mammals sleep elbow-to-elbow in the well-sheltered tunnels of the Ostwall fortification, a largely forgotten war site near the town of Miedzyrzecz, not far from the German border.
