Lich Castle

Lich Castle, a historic structure in the old town of Lich in the Gießen district, Hesse, is an example of late medieval and early modern aristocratic architecture. As the former family seat of the Princes of Solms-Hohensolms-Lich, it shapes the townscape.
History+
The castle's origins lie in several predecessor buildings, including Warnsberg Castle of the Lords of Münzenberg. After their extinction in the 12th century, the Lords of Falkenstein took over, building a valley castle to secure the Wetter river crossing. This moated castle, surrounded by ramparts and a ditch, formed the core of the later urban settlement, which received town rights in 1300. Under Philipp III and Kuno von Falkenstein, a rectangular moated castle with four corner towers was built in the late 13th and early 14th centuries. In 1409, Lich passed to the House of Solms. In the 16th century, lower defensive towers were added. A serious incident occurred in 1606 when a tower collapsed; the planned reconstruction was prevented by the Thirty Years' War.
