Saint Lawrence’s church (Sankt Lars) was built in the central parish around 1210-1220. In the same cemetery a German parish church, Holy Trinity (Drotten in Swedish), was built around 1240. The church was abandoned after the Reformation. Architecturally, Saint Lawrence has its models in Orthodox churches, and it has been wrongly suggested that it would have been a Russian church. It’s more reasonable to imagine an architect influenced by Russian architecture. Sometimes the church has been called Saint Anna (Sankta Anna) the mother of the Virgin Mary.
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.
