Kastell Lostmarc'h, Oppidum in Crozon, France
Kastell Lostmarc'h is an Iron Age fortified settlement located on a rocky headland jutting into the sea near Crozon, Brittany. The site features two rings of stone and earth walls about 2 to 3 meters high, still visible today with surrounding ditches that once formed its defenses.
The site dates to the Iron Age and was built as a defense against invaders, with inhabitants using the rocky terrain to create a stronghold. Around the 1600s, the place was reused as a coastal guard post to protect sailors and fishermen from sea hazards.
The name Lostmarc'h comes from Breton and means "the tail of the horse", inspired by the rocky points at the end of the coast. The horse figure is rooted in local culture and stories about the sea deity Poseidon.
Access is by walking path from nearby villages with gentle uphill sections and coastal views. Wear sturdy shoes and be careful on uneven ground, especially around the rocky outcrops and cliff edges.
Archaeologists discovered pottery fragments and ancient tools here dating back several thousand years, showing how long the place has been inhabited. The pottery styles help researchers understand the exact time period and how earlier inhabitants lived.
