The Porte d’En-Haut is one of the four gateways providing access to the medieval walled town. As its French name indicates, it is located in the upper area of the town, to the east, and leads to the old Saint-Martin area (road to Laval and Paris). Its two towers, connected by a porch dwelling, are topped with machicolations. In the 15th century, it was protected by a barbican, a fortified structure from which cannons could be fired. In 1835, the Town council decided to demolish it all. To the left of the gateway stands La Bridole tower, and to the right, the Prisoners’ tower. Soon after 1878, a walkway was built in the moat linking the outer walls to the counterscarp, strengthened in 1591 by the prow, an artillery stronghold.
