Santiago Cathedral

A special issue on the cathedral of Santiago de Compostela: its history, the Portico of Glory and its stone musicians, the façades and the interior.

A thousand years of stone

The cathedral’s story begins with a tomb. In the early ninth century, Bishop Theodemir of Iria identified a burial in the forest of Libredón that came to be held as that of the Apostle Saint James. King Alfonso II had a small church built there. A larger one followed, built by Alfonso III, which Almanzor destroyed in 997.

The cathedral we know today was begun in 1075, in the reign of King Alfonso VI and under Bishop Diego Peláez. Its first master builder was Bernard the Elder. Work moved forward under Diego Gelmírez, the first archbishop of Santiago, and Master Mateo completed it with the Portico of Glory. The cathedral was consecrated on 21 April 1211.

It is a great Romanesque pilgrimage church: a Latin-cross plan, three naves, an ambulatory around the altar and a gallery running around the whole building. On the outside, the Romanesque stone was wrapped during the sixteenth, seventeenth and eighteenth centuries in a Renaissance, Baroque and Neoclassical skin. That is why the cathedral has two faces: the medieval one inside, and the Baroque one facing the city.

A book and a road

In the twelfth century the Codex Calixtinus, the great book of the pilgrimage, was compiled in Santiago. It contains the liturgy of the Apostle, accounts of miracles, a guide for pilgrims and one of the oldest polyphonic repertoires in Europe. It is kept in the cathedral archive.

The cathedral is the goal of every Way of Saint James. Since 1985 the old town of Compostela has been a World Heritage Site.

In this special issue

We take the cathedral part by part, in entries that can be read on their own:

  • The Portico of Glory: Master Mateo’s great work, arch by arch.
  • The musicians of the Portico: the twenty-four elders and their instruments, with a video.
  • The façades: Praterías, Obradoiro, Azabachería and Quintana, with the Holy Door.
  • The interior: the high altar, the Apostle’s crypt, the organs and the botafumeiro.
  • Who was Master Mateo?: what we know about the Portico’s author.

The cathedral is also part of our Sacred heritage route of Galicia, where it comes first.
