The Governor's Citadel and Palace in Bastia dates back to the 14th century. The former palace of the Genoese governors houses the municipal museum, formerly the Ethnology Museum of Corsica.Abutting the old fortress tower and decorated with a 14th-century campanile, the Palace of Governors over the centuries guarded Terra Nova and beyond the ramparts of the Old Port. The city has undertaken a program of renovation of the palace under the direction of architects Cléris Daniel and Jean-Michel Daubourg.
Besides the renovation of the palace the work helped to rebuild the part of the monument that was destroyed in 1943 during the fighting for the liberation of Corsica. The new museum was inaugurated in June 2010. The museum collections are organized into four themes: birth and urban growth, centre of power, cultural centre, and the Palace of Governors. The turret of the submarine Casabianca was preserved in the courtyard until the renovations.
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
