Burg Steinbrück, Water castle ruin in Steinbrück, Söhlde, Germany

Burg Steinbrück is a water castle and ruin in Söhlde, Germany, surrounded by a protective moat. The complex consists of several connected structures with vaulted passages and a massive keep with underground chambers.

Built between 1370 and 1383, the castle served as a border fortress between two regions. A century later, parts of the complex were repurposed for entirely different functions.

The name Steinbrück comes from the stone road bridge of the trade route that crossed the Fuhse here, not from quarrying; the castle was first called Burg zur Steinbrücke. Since 1956 the Kehrwiederturm has served as the Protestant Kehrwiederkirche, consecrated by Bishop Johannes Lilje. The Förderverein Burg Steinbrück, with over 150 members, works to maintain the site, and medieval-market-style events are occasionally held on the grounds.

The site is partially accessible, with the best visiting opportunities during organized events or guided tours. It is worth checking current accessibility beforehand since restoration work is ongoing.

The Kehrwiederturm, a gun tower built in 1573 with walls up to five metres thick and five embrasures, was converted into the Protestant Kehrwiederkirche in 1956 and consecrated by Bishop Johannes Lilje on the third Sunday of Advent. It remains in church ownership with its cemetery, while most of the castle passed into private hands in 2013.
