The former Lectoure Cathedral dominates the town and the belfry tower of 1488 can be seen at a distance as the town is approached. The repairs and modifications of the cathedral go back to the 12th century. The unadorned west front erected in the 15th century has been modified through the ages, and niches above the door have all but melted away due to the fragility of the limestone.
The nave was vaulted at the end of the 12th century, then repaired in 1480. Vaulted chapels were added at the beginning of the 16th century and more alterations followed in the 17th and 18th centuries. The choir and apse were also reconstructed at the beginning of the 16th century, and the five square apsidal chapels were completed. The ambulatory was created in 1600 by introducing ten cylindrical piers, and the carved early 17th century choir stalls were placed here in the 19th century. The stained glass is typically 19th century with a Tree of Jesse in the Chapelle de la Sainte Famille.
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.
