halted several times and, according to the , the last stone was laid in 1122. But by then, the construction of the cathedral was certainly not finished. The cathedral was consecrated in 1211 in the presence of king Alfonso IX of Leon. According to the the architects were "Bernard the elder, a wonderful master", his assistants Robertus Galperinus and, later possibly, "Esteban, master of the cathedral works". In the last stage "Bernard, the younger" was finishing the building, while Galperinus was in charge of the coordination. He also constructed a monumental fountain in front of the north portal in 1122. The city became an episcopal see in 1075 and the church its cathedral. Due to its growing importance as a place of pilgrimage, it was raised to an archiepiscopal see by pope Urban II in 1100. A university was added in 1495.
