The eastern part of the 400 metre-long Husovo Square in Rakovník is dominated by the high Gothic Church of St. Bartholomew, a 14th-century structure. The church was built on the site of an older church dedicated to St. Nicholas. Adjacent to the church stands a bell tower dating from 1495. It is considered as the most precious gothic bell tower in the Czech Republic and one of the most precious in Europe. The bell has a diameter of 1.6 metres.
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.
