Monastery of San Martiño Pinario

The monastery of San Martiño Pinario (San Martín Pinario in Castilian) was a Benedictine monastery in the city of Santiago de Compostela, Galicia, Spain. It is the second largest monastery in Spain after San Lorenzo de El Escorial.

Little remains of the original medieval buildings, as the monastery has been largely rebuilt since the sixteenth century. The monastery was closed in the nineteenth century in the Ecclesiastical Confiscations of Mendizábal. The buildings currently house a seminary.
