The Parroquia El Salvador, originally part of the Monastery of San Salvador, became an independent parish after the confiscation. The temple preserves Romanesque elements on the walls of the nave and some windows. In its Romanesque portico, completed in 1072, there are paintings in its 15th-century vault. From the outside it stands out for its imposing staircases that create an effect of majesty.
