History+
The origins of Mechelgrün Moated Castle date back to the 12th century, with its first documented mention in 1267. In the 14th century, the castle was expanded to resemble a palace. For a long period, until the mid-15th century, it was owned by the Rabe family, a noble lineage in the Vogtland. A member of this family, Johannes Rabe von Mechelgrün, acquired Wildstein Castle in 1298. In 1465, the complex was destroyed but rebuilt with four corner towers, and in 1475, a chapel was added to the eastern tower. After a fire in 1670, which reduced the castle to its foundations, a slightly altered reconstruction took place around 1675.
