St. Martin's Basilica (Mondoñedo)
Mondoñedo, ES
The Basilica of San Martín de Mondoñedo, located in the municipality of Foz (Lugo, Galicia, Spain), is considered the oldest cathedral in Spain, since in the 9th century it was the seat of two bishoprics of the kingdom of Galicia: one transferred from Dumio, in the district of Braga (Portugal), and another moved from Bretoña, in the province of Lugo. The current building is Romanesque from the end of the 11th century and the strong buttresses are the work of the 18th century.
