Aleth, Archaeological settlement on Brittany coast, France
The archaeological site of Aleth stands on a promontory at the mouth of the Rance river, featuring ancient stone fortifications and Roman walls.
Established by 80 BC, Aleth served as the capital of the Celtic Coriosolites people and developed into a strategic Gallo-Roman town with port facilities.
The remains of Aleth Cathedral, constructed between the 9th and 12th centuries, display a combination of Gothic and Romanesque architectural elements.
Visitors can explore the ruins of the former settlement in Saint-Servan, which is now integrated into the modern commune of Saint-Malo.
The site's name originates from the Gaulish term Al-etum, referring to the rocky elevation that provided natural defenses for the settlement.
