The fortified Flemish castle château de Grand-Rullecourt with its towers and crow’s-foot gables overlooks the road from Avesnes-le-Comte to Lucheux. The lords of Rullecourt were the generous donors of land to the Abbey of Mont-St-Eloi. Joan of Arc passed there as a prisoner in 1430. Antoine-Constant de Hamel started to build the new castle in 1746.
After the French Revolution, the chateau was sold as a national asset. His grandson bought it back but couldn't afford to keep it. It later belonged to Captain Wallerand de Hauteclocque, who was killed during World War I. After the war, the property was sold in parts. Later rented as a holiday camp, the castle was left uninhabited for some time. The daughter of Mr. Voisin, Mrs. Buneau, sold the chateau to Patrice and Chantal de Saulieu and their children on 24 December 1987. Today Château de Grand-Rullecourt is a Bed & Breakfast hotel.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
