The north transept and the west tower date from the 13th century. The font is Norman. The south aisle is 15th century.
The church was restored in 1847-48 when the south chapel was demolished. From 1872 to 1874 the north walls of the nave and chancel, and the whole of the north transept was rebuilt. The pews were removed and open seating was provided.
The ecclesiastical parish is the responsibility of the Rector of Lanteglos-by-Camelford, and Advent has been associated with Lanteglos since medieval times.
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.
