Nassauer Haus

Nassauer Haus is a five-story residential tower built from red sandstone with a pyramid-shaped roof at the corner of Königstraße and Karolinenstraße. The structure displays Romanesque features with decorative oriel windows added later, and today houses a pub in its vaulted cellar.

The tower was built between the 12th and 13th centuries as a defensive residence. Between 1422 and 1437, decorative oriel windows were added, transforming its appearance and adapting it to newer living standards of that era.

The name comes from the Nassau family who used this tower as their residence. You can still see how the thick walls and narrow windows show that such towers served both as homes and defenses at the same time.

The building is centrally located at Königstraße 20 and easily accessible on foot from the city center. If you want to go inside, you can visit the pub in the lower level, where you can see both the historic cellar vaults and enjoy a drink in this old space.

This is the last surviving Romanesque tower house of its kind in the city, having retained its original walls despite wartime damage. Its location at a prominent street corner shows how wealthy families used such visible positions to display their status and power.
