Viewpoint over Fort l'Écluse
A strategic passageway with an ingenuous construction:
The first military constructions in the Défilé de l'Écluse were built during the 1st century B.C., under Julius Caesar's orders. The first fortified house was later built by the Lord of Gex during the 13th century. The site became fortified and developed over time in response to attacks, particularly against the Austrians, Bernese and Genevans. After a clash and significant damage in 1815, the fort was rebuilt, strengthened and extended with a second fortification 200 metres higher up. Many tunnels and passageways link the two structures together. Its position on an abrupt cliff allowed for long-distance views and shooting in order to defend the Défile both upstream and downstream.
From the Vierge de Léaz belvedere parking lot, head up “rue Saint Armand” on your right, and take “Chemin des Moulins” after the washhouse and the school. When you reach a first belvedere with a sign on the Château de Léaz, take the rocky trail to your right to reach the Vierge de Léaz belvedere. Return the same way.
Recommendations: If the Vierge de Léaz belvedere parking lot is full, a second parking lot can be found 100 metres to the north, near the village’s cemetery.
Fort de l'Écluse is open to the public. To find out about opening times and prices, and for any other information, contact the Terre Valserine Tourist Office.
