O Cebreiro is a parish of the municipality of Piedrafita do Cebreiro (Lugo, Galicia). In its architecture the pallozas, stone houses with thatched, stand out. Some interesting sights are the Church of Santa María (Romanesque, 9th century), which houses a Romanesque chalice, from the 12th century, and the San Giraldo de Aurillac hostel, the busiest from Roncesvalles, since it has been running since the 9th century.
