The Château de Flers, bearing the date "1661" on its facade, was originally the residence of the Lords of Flers. It was destroyed during the French Revolution of 1789, but not confiscated because it belonged at that time to a foreign nobleman, the Baron de Diesbach. In the 19th and 20th centuries, the château enjoyed a second life as a farm: the salon, apartment, and reception hall were converted into a barn, cowshed, and stables. In 1968, with a view to the development of a new town east of Lille, the château was expropriated by the state and, in 1973, entrusted to the Public Institution for the Development of the New Town of Lille-East. The municipality of Villeneuve-d'Ascq became the owner in 1986. They completed the restoration of the building, which had been entrusted from the outset to architect Maurice Salembier. After restoring its 17th-century appearance, the Château de Flers began a third life as a municipal building in 1991. Today, it houses various services, the tourist office, rooms for official receptions, and a museum. Source: Information board on site

The Citadel of Lille was built between 1667 and 1670 on the orders of Louis XIV when he conquered the city. It is Vauban's first major fortified work. The large wood surrounding the citadel is surrounded by the Deûle and its canals. You will find superb single tracks there, with small bumps and passages over roots.

This historical monument, under the control of the Ministry of Defense, is the Citadel of Lille and the Museum of the Sedentary Artillerymen. It is called the Queen of Citadels, built by Vauban in 1670. The building is in the shape of a regular pentagon, reinforced by powerful bastions, within which the buildings are arranged in a star shape to form a large central courtyard. Around it and open to the public at all times is a beautiful park (with a zoo and a playground), but if you stay on the path, you walk along this star.
