Warmsdorf Castle, Heritage castle in Warmsdorf, Germany.

Warmsdorf Castle is a water castle in Salzlandkreis that was built in its current form between 1550 and 1552. The structure combines traditional German architecture with medieval fortification elements and is surrounded by water features.

The castle was first recorded in 1269, possibly existing since the 10th century. Around 1205 the von Warmsdorf family appeared, and by 1339 the Ilsenburg monastery was among the owners. In 1532 it returned to the princes of Anhalt; after the 1546 partition, Georg III converted the medieval moated castle into a residence, adding the north wing in 1552. In 1603 it passed to Anhalt-Köthen, and in 1847 to the Dessau line.

The name Warmsdorf comes from the noble family von Warmsdorf, first mentioned around 1205 with Eberhard von Warmsdorf. In the castle garden, the Georgskapelle stands near the site of the old village church; it houses a small exhibition on Prince Georg III, whose study was located there from 1551 to 1553.

The castle is located in Gusten at coordinates 51.77898 latitude and 11.58164 longitude and is easily reached by public transport. Visitors should wear sturdy shoes, as access to different areas of the building involves stairs and uneven surfaces.

The medieval bergfried, a 12th- to 13th-century keep, was demolished in the 1960s for safety reasons, so the round castle's core tower no longer stands. Ratke was held in the Schlossturm for nine months in 1619, accused of heresy, fraud and links to the Rosicrucians.
