A Pastoriza is a municipality in the province of Lugo, in the autonomous community of Galicia, Spain. It belongs to the comarca of Terra Chá. It has a population of 3,911 (Spanish 2003 Census) and an area of 175 km². The most important river in Galicia and one of the most plentiful rivers of Spain begins here, the Miño River.
The artistic heritage of A Pastoriza is noted for its many stone crosses, chapels and churches that make up the rural municipality. The Temple of Breton is considered the cradle of the diocese of Mondoñedo-Ferrol because it was the ancient Britoniensis episcopal until the eighth century. Several authors defend the existence of a British Christian society in this area. It is believed that it was they who founded a Breton bishopric, Britonia.
