Saint-Pons-de-Thomières Cathedral was formerly the seat of the Bishopric of Saint-Pons, founded like a number of bishoprics in the region in the aftermath of the suppression of the Albigensians. By a Papal bull dated 18 February 1318, Pope John XXII created the see by elevating the abbey of Saint-Pons, which had been here since its foundation in 936 by Raymond, Count of Toulouse. The bishopric was abolished by the Concordat of 1801 and merged into the Diocese of Montpellier.
The Romanesque abbey church became the present cathedral. It takes its dedication, like the town and the abbey, from Saint Pontius of Cimiez. It is particularly known for the carvings on and around the portals. During the French Wars of Religion the choir was destroyed; it was replaced with the present neo-classical east front.
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.
