The greatest military architect of the 17th century, Sébastien le Prestre de Vauban, designed this massive fortress, shaped like a five-pointed star, after the capture of Lille by France in 1667. Made of some 60 million bricks, it still functions as a French military base. It stands at the north-eastern end of boulevard de la Liberté. Outside the 2.2km-long outer ramparts is the city centre’s largest park. Guided tours are available on Sundays.
