A Pastoriza is a municipality in the Spanish province of Lugo. It has a population of 3,911 (Spanish 2003 Census) and an area of 175 km². It belongs to the Terra Chá region. In this county the most important river in Galicia begins and one of the most plentiful in Spain, the Minho 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.
