The construction of the current façade began at the beginning of the 16th century under the design of Juan de Badajoz. Despite the time of construction, the Gothic style is still used instead of the Renaissance style.

A low portico was built with three arches and three doors giving access to each of the naves. It is covered with an almost flat ribbed vault. The central doorway, the most important both aesthetically and in terms of size, is crowned with a relief of the Transfiguration and next to it some figures in bas-relief representing Fruela I and Alfonso II the Chaste. A little further down, there are medallions depicting the infant Jesus and Saint John the Child.

The doors were made in the 18th century in walnut. The door of the central nave contains in the centre of each of its leaves an image of San Salvador and Santa Eulalia de Mérida, both patrons of the cathedral and of the Principality of Asturias. Access to the church is through the door on the left.
