Tumulus de l'île Carn, Neolithic burial mound in Ploudalmézeau, France.
The stone cairn measures 30 meters in diameter and 8 meters in height, containing three parallel passage graves on the tidal island.
Archaeological excavations conducted between 1953 and 1972 revealed that the central chamber dates back to 4200 BCE, making it among Europe's earliest megalithic burials.
The name Carn derives from Celtic languages, meaning stone heap, reflecting the ancient engineering methods used to construct burial monuments.
Visitors can access the island only during low tide, with guided tours available in summer through the Ploudalmézeau tourist office.
The central chamber features a distinctive q-shape design, while archaeologists discovered pottery fragments that defined the Carn style classification.
