Thuisbrunn Castle is located centrally within the parish of Thuisbrunn in the municipality of Gräfenberg in the Bavarian province of Upper Franconia. After having been destroyed and rebuilt several times, the castle is now in private ownership.
The spur castle was first mentioned in 1348 and Lord Hiltpolt of Mayenthal named as the castle lord (Burgherr) of Thuisbrunn. In 1388, during the South German War of the Cities, it was destroyed by Nuremberg troops and thereafter given to the burgraves of Nuremberg as a fief. In 1420 the castle was again wrecked during the Bavarian War by troops of Duke Louis of Ingolstadt. However, when the village of Thuisbrunn was destroyed in July 1449 by Nuremberg soldiers and again in 1460 during the Princes' War, the castle remained undamaged.
In 1553, during the Second Margrave War, the castle was once more destroyed by Nuremberg troops. By 1558 only the district office (Amtshaus) and the bergfried had been rebuilt. During the Thirty Years' War and thereafter, Thuisbrunn and the castle were plundered seven times by Imperial, Swedish and Bavarian soldiers. In 1667, the Vogtei office was probably built in place of the old district office; apart from this house and the bergfried the castle remained a ruin.
In 1816, the cartographer, Johann Christoph Stierlein, made for the first time a very precise map of the castle area and its surviving buildings. Following the seizure of the estates by the Kingdom of Bavaria in 1806 during the Napoleonic Era, the Vogtei office was used as a forestry office. Towards the end of the Second World War the castle was shelled by American troops. In 1961 it was sold into private ownership.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
