Rammelburg Castle

Rammelburg Castle is located in the wooded surroundings of the Lower Harz and was built around 1190 by the Counts of Arnstein. The first documented mention as "castrum Rammeneborch" dates back to 1259. In 1296, the owners of the castle were the Counts of Falkenstein, in 1334 the Counts of Reinstein, and in 1387 or 1400 the Counts of Mansfeld. In the 16th century, the residential wing was built in the west wing. In 1554, the castle was besieged by Duke Heinrich of Braunschweig. After this, ownership changed in 1637 to the Lords of Stammer and in 1720 to Karl August Freiherr von Friesen.
