Münzenberg Castle (German. Burg Münzenberg) is a ruined hill castle in the town of the same name in the Wetteraukreis, Hesse, Germany. It dates from the 12th century. It is one of the best preserved castles from the High Middle Ages in Germany. The exact time of the construction is controversial in research. It is generally assumed that during the time of Kuno I, significant parts of the ring wall around the main castle, the Romanesque palace, the eastern keep, the gate building with the chapel above it and parts of the kitchen building were built. This construction phase is said to have ended in 1174 at the latest without the circular wall being completed. The palace remained unplastered, the kitchen building a torso. In 1846 work began on restoring individual parts of the castle and securing the masonry. Just one year later, the eastern keep could be climbed. However, plans for a romantic restoration of the castle were dropped by the counts of Solms-Laubach, by then owners of the castle. In 1935 they sold it to the People's State of Hesse. Today, the State Palaces and Gardens of Hesse maintain the castle ruins.
