Zwinger

The Zwinger is a substantial sandstone tower in Goslar with thick walls and a circular footprint that rises through multiple levels. Its interior is divided across several floors for different uses including dining, lodging, and displays.

This fortification was built in 1517 on Thomaswall to protect the imperial city of Goslar from potential attacks originating from the Rammelsberg hill position. The construction reflected the city's defensive strategy at that time.

The tower displays two sandstone tablets with the coats of arms of the German Empire and Goslar, symbolizing its connection to medieval rule. These emblems remain visible reminders of the city's historical authority today.

Visitors can explore different levels of the tower, though some areas may be restricted while others remain accessible to the public. Plan your visit to see both the exterior structure and the interior spaces.

The builders mixed the mortar with horsehair, curds, goat milk, and ox blood to achieve proper hardening of the structure. This unusual recipe shows the resourceful building methods used in that era.
