01 · Why Go

Before the Altars

Come because this is where the custody of the tomb began. A community was placed here to keep watch over the shrine long before the cathedral reached its present form, and a community is still here. The museum holds the Ara de Antealtares, and the church offers something the cathedral cannot: quiet.

Founded to Serve the Shrine

Catholic tradition in Galicia holds that when the tomb was identified in the ninth century, King Alfonso II established a monastic community beside it to guard the site and maintain worship there. The house took its name from its position, east of the tomb and before the altars raised over it, and was later dedicated to Saint Pelagius of Córdoba. Benedictine monks held it until the end of the fifteenth century; from 1499 it has been a monastery of enclosed Benedictine nuns. The buildings you see are not the ninth-century foundation. They are a Baroque rebuilding, raised on a site that has never been abandoned.

Read the Place

The house that was set to keep watch.

Read San Paio as custody. Its position, its name and its survival all come from one job: staying beside the tomb.

  1. 01 Start with the name Antealtares means before the altars. The house was placed east of the tomb, in front of the altars raised over it, and the name has outlasted every rebuilding.
  2. 02 Read the wall, not the facade What most visitors see is the long blank monastic wall along the Quintana. That wall is the enclosure, and it is doing exactly what it was built to do.
  3. 03 Then read the Ara The stone kept in the museum has been venerated for centuries as the altar of the Apostle's first disciples. The tradition is old and continuous; it is not the same thing as a dated excavation.
  4. 04 End with the community Benedictine nuns still live behind that wall. This is not a preserved monastery. It is an occupied one, and the silence in the square at night is partly theirs.

The name Antealtares means before the altars: the house was founded east of the newly identified tomb, in front of the altars raised over it.

The community became a house of enclosed Benedictine nuns at the end of the fifteenth century, and remains one.

02 · Monastic Identity

A monastery is best understood by the life it was built to sustain.

  • The building is Baroque; the site is ninth-century. Do not read the walls as the age of the foundation.
  • The blankness of the Quintana wall is the point. An enclosed house turns inward, and the square gets its severity from that decision.
  • The Ara is venerated, not excavated. Catholic memory has held it as the disciples' altar for centuries, which is a different claim from an archaeological one, and the more honest one to make.

    The Ara de Antealtares

    A marble slab on a semicylindrical base, kept in the museum and venerated in long-standing tradition as the altar raised by the Apostle's disciples at his burial place.

    The church doorway on the Rúa Sacra

    A Baroque front of 1707 with Saint Pelagius standing in the niche above the door, on one of the quietest short streets in the old town.

  • 03

    The monastic wall on the Quintana

    The long unbroken wall that closes the eastern side of the square is the enclosure itself, and it is why the Quintana feels the way it does.

    The sacred art museum

    Open to the public since 1971, holding sculpture, painting, silverwork and manuscripts from a community that has kept this site for over a thousand years.

The present Baroque building is not the ninth-century foundation, and the record says so.
