The reformed church of Dronrijp, originally named St. Salvius, is a one-aisled building with a polygonal choir. The original smaller Romanesque church was rebuilt in Gothic style in 1504. The northern wall of the nave still shows Romanesque details. The tower was built in 1544 and is in late-Gothic style. Unusual for this province is the presence of an octagonal upper part.
In the 17th century portals in Classical style were added to both the nave and the choir, while the entire church was plastered and painted. During a restoration in 1958-1959 this coat was removed from the tower only.
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.
