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.
Open on the 2nd and 4th Sundays in the month from April to October. Also open by arrangement.
