Fortifications romaines des Cluses

The Fortifications of Les Cluses are a military complex with two forts standing on opposite sides of a river valley, connected by defensive walls and structures along an ancient road. The remains demonstrate Roman engineering adapted to mountain terrain.

The site was constructed between the 3rd and 4th centuries to control a key mountain passage connecting two major regions. This period marked when Rome needed to strengthen its border defenses.

The fortification displays Roman military construction with square towers and stone walls built to control movement through the mountains. Walking through the site, you see how soldiers stationed themselves to monitor and defend the pass below.

The archaeological site spreads across the Albères mountains with sections on both public and private land. Visitors should wear sturdy shoes because the terrain is uneven and steep in places.

One section of the complex contains three square towers and a defensive wall with a partially paved walkway that shows how Romans built practical structures even in difficult mountain terrain. Such well-preserved construction details are uncommon at other mountain fortifications.
