Sarria is a municipality in the province of Lugo, northwestern Spain, in the autonomous community of Galicia. Sarria is the most densely populated town on the Camino in Galicia, with 13 700 inhabitants. It is a popular starting point to begin the Camino the Santiago; many pilgrims choose Sarria because the distance from this point to Santiago is the minimum distance to get the Compostela (certificate of completion).The town of Portomarín was constructed and built next to a Roman bridge over the Minho River and rebuilt in the Middle Ages. In the 1960s the Miño River was dammed to create the Belesar reservoir, putting the old village of Portomarín under water. The most historic buildings of the town were moved brick by brick and reconstructed in the new town, including its castle-style main church: Church of San Juan of Portomarín.
