St. George's Cathedral, also called Wiener Neustadt Cathedral is the cathedral of the military ordinariate and a minor basilica. The church, begun in 1440 on the west side of the castle of Wiener Neustadt, was commissioned from the architect Peter von Pusica by Frederick IV, Duke of Austria. At the end of the work the church was dedicated to St. Mary and consecrated in 1460. In 1479 the Order of the Knights of St. George established their headquarters in Wiener Neustadt, and the patron of the church became St. George. After the abolition of this chivalric order in 1600, the church was entrusted first to the Cistercians and later the Piarists. In 1608 and 1616 two fires damaged the castle and the church, which were repaired by initiative of Maximilian III.
With the foundation of Teresian Military Academy on December 14, 1751, the church was closely tied to the fate of the castle as the headquarters of the military school. The castle and church were completely destroyed in bombing during the Second World War on March 12, 1945, but reconstruction began the following year, to be completed only in 1958.
Since 1963 the church has been home to the Military Ordinariate, as a result of which it was elevated to the status of cathedral. On 13 December 1967 it also became a minor basilica.
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.
