Aleth Cathedral, Gothic cathedral ruins in Saint-Servan-sur-Mer, France.
The remains of Aleth Cathedral span 50 meters in length and 18 meters in width, featuring stone walls that outline its original structure.
The cathedral served as the center of an episcopal see during the 9th century until Norman invasions caused substantial destruction in the 10th century.
The structure earned recognition as a monument historique inscrit, marking its place among nationally protected architectural heritage sites in France.
Visitors access the cathedral ruins through a coastal pathway called corniche d'Aleth, which connects to other historical sites in Saint-Malo.
The cathedral's location on a peninsula at the Rance estuary influenced the development of Saint-Malo as a defensive stronghold in later centuries.
