Rogätz Castle, Medieval castle in Rogätz, Germany.

Rogätz Castle is a stone fortress in the town of Rogätz, Germany, with medieval architecture and defensive structures. The building displays typical features of a fortress from this period, with preserved walls and towers that originally served to control and protect the region.

Rogätz Castle, first documented in 1144 when Count Otto von Hillersleben gave the village to the Bishop of Havelberg, began as a 10th-century border fortress against the Slavs. Its only surviving structure is the Klutturm, a stone tower. In 1449 the Treaty of Zinna awarded overlordship to the Archbishopric of Magdeburg, and in 1369 the archbishop sold castle and lordship to the Alvensleben family. Imperial troops captured it in 1625; the Danes retook it the next year, but buildings burned except the Klutturm and were not rebuilt.

The castle chapel tower, with its baroque hood of 1700, became the village parish church when the Reformation was introduced in 1558. Inside, grave slabs and a carved baptismal font recall the von Alvensleben lords, who live on in local ghost stories and legends. The legend of a golden chain encircling the tower foundation stems from the castle's former customs and staple right on the Elbe.

The castle itself was never rebuilt after 1626; only the Klutturm survives, rising above the Elbe steep bank near the mouth of the Ohre. The site lies on a grassy, tree-covered slope, and the former upper and outer baileys are now occupied by farmyards. The village church tower, once the castle chapel, carries a baroque hood dated 1700.

The castle's only surviving structure is the Klutturm, a tall square stone tower with a flat top and a small roofed structure at its centre. The four-winged Renaissance palace and the other castle buildings were destroyed in 1625 during the Thirty Years' War and never rebuilt, so their appearance can no longer be determined.
