Monastery of San Paio de Diomondi

In the year 976, Senior, niece of Bishop Hermogius of Tui, who was also the uncle of Saint Pelagius (Paio), to whom the monastery would later be dedicated, made an important donation to this establishment. The community residing in Diomondi was under the jurisdiction of the Cathedral of Lugo and did not depend on another monastery; it may even have been a secular abbey. Between 1138 and 1164, the monastery changed its original dedication to that of San Paio. After a period of scant documentation, by 1138 it was already a possession of Alfonso VII, and in 1164, Fernando II granted it to Fernando Odoariz and his wife, Teresa Muñiz. However, in 1178 the monastery was once again under the control of the Church of Lugo, as confirmed by Pope Lucius III in a papal bull issued in 1185.

This structure could be the successor of the ancient residence of Bishop Odoarius of Lugo and Braga, who took refuge here during the Saracen invasion and is believed to have died at this site. The church, with a single nave and semicircular apse, is thought to have been built between the last quarter of the 12th century and the early 13th century. On the south side, it has an attached sacristy, and on the north side, the episcopal palace. This latter structure was in ruins, and part of it collapsed at the end of 2010; it has since been restored and converted into a pilgrims' hostel.
