Château de Durfort was erected on a rocky piton which overlooks the valley of the Orbieu. The present ruins are those of a strengthened habitat, including a chapel, dwellings with rectangular windows and a tower. High thick walls, cellars and wells, arched rooms of square buildings, corner turrets, watch towers and a main tower are still visible.
There is no documentary evidence for the initial construction of this fortress. The earliest written references mentioning the castle date from 1093.
After the Crusades against Cathars in the mid-13th century, the royal power confirmed its conquest of the region by building five large fortresses and a network of watch towers. The Château de Durfort was written into this defensive system, aimed at protecting the new frontiers of the Kingdom of France.
In 1659, Louis XIV signed the Treaty of the Pyrenees with the Kingdom of Spain. This treaty altered the borders, giving Roussillon to France. The frontier advanced to the crests of the Pyrenees and the various fortresses of the region lost their strategic importance. The Château de Durfort was, therefore, altered to make it more comfortable.
In the 18th century, the castle seems to have been abandoned but its isolated position served to preserve its ruins. Today, the castle is private property; it may be visited free of charge with prior authorisation from the owners. The building is not preserved or maintained; there is a risk of falling stones.
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.
