St Catherine`s Church in Trent, first mentioned in a document dating to 1318, is special due to its rib-vaulted choir (c.1400) alongside the middle axis. Today's nave was built at the end of the 15th century in the form of a Gothic hall. Apertures in the wall of the three-story west tower indicate that it served a defensive purpose at times of war. The curved dome was added to the tower only in 1602. The elaborate carved Baroque altar (1752), the Protestant confessional (1754) and the baptismal font stand were built by the then-famous Stralsund master Michael Müller. A large number of epitaphs and memorial slabs point to the von Platen patron family, whose family seat was in Granskevitz.
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.
