Ruins of the old observant convent San Francescu Vechju founded in 1236 by a disciple of Saint Francis. Completed around 1257, he owned a navy at a place called Roncu and occupied the whole of the point. It will be ruined by the siege of Calvi in ??1554.
Only a few stones remain today, but the site offers a magnificent view of the sea, the Revellata, the Citadel and the Roncu.
