Fort Jouy, which is located between Toul and Verdun, was built between 1883 and 1885. It is a Séré de Rivières fort built entirely of freestone and it has never been modernised. It is pentagonal in shape, with 4 courtyards and a moat defended by 4 caponiers, one of them double. The fort still has its original entrance, drawbridge and armoured gate.
