Schloss Bartensleben, Baroque palace in Erxleben, Germany.

Schloss Bartensleben is a Baroque palace built on an island surrounded by a wide moat in Erxleben. The structure comprises three wings with distinctive mansard hipped roofs and is connected by a bridge across the water.

A moated castle (Wasserburg) stood here from around 1400, when Ludolf I. von Veltheim was enfeoffed with the site by the Archbishop of Magdeburg. In 1467 Hilmar I. von Veltheim received the village of Bartensleben. The von Veltheim family replaced the old water castle with a Baroque palace in the mid-18th century; in 1757 Heinrich Adrian von Veltheim added the central and western wings, with Rococo interiors. After 1945 the family fled expropriation, and the palace later served as a Soviet and NVA facility, a women's spa, and a retirement home until 1991.

The village of Groß Bartensleben long remained a Fideikommiss, an entail keeping the estate in the von Veltheim family even without a direct male heir; the property covered about 1,290 hectares and ran a sugar factory. The park beside the castle probably developed in the 18th century from an earlier Baroque garden and has been restructured since 2008.

The site is accessible by crossing a bridge, and the wide moat provides good views from the exterior. Visitors should be aware that the interior now serves as a nursing home, so access is limited.

The dates 1471, 1567 and 1578 carved on different parts of the building come from older structures reused when the Baroque palace was built in the mid-18th century. They show that masonry from the predecessor buildings was incorporated into the new walls.
