Séré de Rivières system
The Fort of the Crèche is a coastal battery of the Séré de Rivières system, whose construction was completed in 1879. It is near Wimereux, in the Pas-de-Calais on the tip of Pointe de la Crèche. It is built on the remains of a Napoleonic defense system consisting of Fort Terlincthun and a sea fort, opposite the tip of the cape, of which only the foundations remain.
