The Cathedral of Saint Mary of Bayonne is the seat of the former Bishops of Bayonne, now the Bishops of Bayonne, Lescar, and Oloron. The cathedral is in the Gothic architectural tradition.
The site was previously occupied by a Romanesque cathedral that was destroyed by two fires in 1258 and 1310. Construction of the present cathedral began in the 13th century and was completed at the beginning of the 17th, except for the two spires which were not finished until the 19th century. The structure has been much restored and refurbished, notably by Émile Boeswildwald, architect to the French government in the 19th century, and a pupil of Eugène Viollet-le-Duc.
The cathedral stands on the Pilgrimage Way of Santiago de Compostela.
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.
