A Cistercian abbey founded in 1149 by the nobleman Ero de Armenteira, who took the habit in 1162. It belonged to the Clairvaux filiation and is now home to a community of nuns, with a guesthouse.
On the Camino
The first stage of the Spiritual Variant ends here, 20.5 km (12.7 miles) after leaving Pontevedra, and the Ruta da Pedra e da Auga towards Vilanova de Arousa begins. Albergue San Ero is about 750 m as the crow flies.
What to see
The church was built between 1167 and 1225, with a rose window and a doorway of six archivolts on the west façade. It has a Latin-cross plan and three naves. The monastery was secularised in the confiscation of 1837, and in 1989 Trappist nuns arrived from Alloz, in Navarre.
