Hochbunker, Unfinished high-rise bunker in Augustinerhof, Trier, Germany

The Hochbunker is a concrete shelter with thick reinforced walls and a fortified design located in Augustinerhof. The structure features heavy blast-resistant construction, reinforced entry points, and ventilation systems designed to operate during emergencies.

This shelter was constructed during World War II to provide refuge for residents during air raids. It represents one of many defensive structures built by German cities to protect their civilian populations.

The bunker's nickname and role tie it to the Augustinerhof square beside the town hall, where city staff and firefighters ran operations from inside during the war. Its pointed unfinished roof was shaped so a direct hit would glance off and explode on the ground alongside.

The tower stands beside the Rathaus on Augustinerhof square; the flat bunker adjoining it has only one visible storey above ground, and the whole complex keeps two basement levels. The massive walls and narrow, windowless rooms blocked earlier reuse plans, and the bunker has served the neighbouring Stadttheater as a props store. The interior is not described in the sources as open to visitors, so treat it as a structure to view from the square.

The unfinished pointed roof was meant to deflect bombs so they would bounce off and explode on the ground beside the tower. The architect Heinrich Otto Vogel planned sandstone cladding and a slate roof to blend the bunker into the cityscape, but these were never applied. The ventilation machinery still lies unassembled inside.
