Mirepoix Cathedral (Cathédrale Saint-Maurice de Mirepoix) foundation stone was laid by Jean de Lévis on the 6th May 1298. Construction continued, with interruptions, over the next six centuries. The cathedral was restored in 1858 and 1859. The cathedral has the second widest Gothic arch in Europe (after Girona in Catalonia, Spain).
Inside the cathedral vandalism and demolitions has destroyed many treasures but you can still admire a tabernacle, a Christ on the cross from the 14th century and seven paintings by Larivière-Vesontius.
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.
