Colegiata Real de San Isidoro de Leon is one of the most notable and emblematic in all of Spain, was constructed on top of an old church which was dedicated to St. John the Baptist and demolished by Almanzor in 988. Alfonso V rebuilt it and Fernando I reconstructed a new temple in which the relics of San Isidoro and San Vicente were placed, bestowing the church with an extra reverence. The style of the collegiate church was Pre-Romanesque, and subsequently it was completely rebuilt in a Romanesque style, with three naves and a sanctuary with three apses. One of the apses disappeared when it was converted into a Gothic style.
