Mont Saint-Frieux

Mont Saint-Frieux rises 152 meters above sea level, forming part of the Boulonnais region with extensive dune formations atop ancient chalk cliffs.

German forces constructed military installations during World War II, including observation bunkers and artillery positions as components of the Atlantic Wall defense system.

The mountain bears the name of anchorite Frieux, who established a hermitage and monitored Viking movements from this vantage point in medieval times.

Visitors need authorization from the local forest keeper to access certain protected areas, while marked trails allow exploration of permitted sections.

The location contains twenty-nine distinct habitats where Highland cattle graze to maintain the natural balance of the ecosystem.
