NORTHAG War Headquarters Cannerberg

NORTHAG War Headquarters is an underground military facility carved into the limestone caves beneath Cannerberg mountain, with a network of tunnels connecting various operations centers. The restored complex contains offices, map rooms, and control stations that once monitored military activities across the region.

The facility opened in 1955 as NATO's Joint Operations Centre, coordinating military activities across northern West Germany during the Cold War. Operations ceased in 1992 following the end of the conflict.

The bunker embodied NATO cooperation, bringing together personnel from the Netherlands, Britain, Belgium, Germany, and the United States under one roof. This international presence remains visible today through the restored workspaces that show how these nations coordinated their efforts.

Guided tours lasting about two hours lead visitors through the underground complex, and wearing warm clothing and sturdy shoes is essential since temperatures stay cool year-round. The passages have steep stairs and tight spaces, so proper footwear is important for both safety and comfort.

The facility houses a contemporary art exhibition called 'Shelter' by Rob Scholte, featuring a work titled N8W8 that reinterprets Rembrandt's famous Night Watch painting. This unexpected blend of art and military history offers a surprising perspective on the site.
