- Santiago is one of the great monasteries of Europe in the Middle Ages. The
size of its Nave and transept is extraordinary. It has several stages of construction which can be summarized in: first phase, 1065-1101, Bishops Pelaez and Gelmírez built the apses, the chapels, the transept and the first section of the nave; second phase 1101-1122, the bishop Gelmírez built the six storied main doors being Porta Francigena in the north arm of the transept, Porta de Platerías in the south arm and the largest Western Porta ; third phase, 1122-1168, it completed the Nave and the Western Porta; fourth phase, 1168-1211, the Master Mateo, builds the Portico de la Gloria. The stonemason’s signs of the first two phases are of high technical and artistic quality and in the columns are of high dimensions. The master builders of these two phases were from French school.
