The construction of the cathedral was ordered by King Ferdinand III of Castile and Mauricio, the English-born Bishop of Burgos. Construction started on the site of the former Romanesque cathedral on July 20, 1221, beginning at the chevet, which was completed in nine years.The high altar was first consecrated in 1260, then there was a lengthy hiatus of almost 200 years before construction was recommenced. The cathedral was completed in 1567, with the completion of the lantern spire over the main crossing (which rises above a delicate openwork star vault).The architects who directed its construction were a Frenchman in the 13th century and a German in the 15th century. In 1417, the bishop of Burgos attended the Council of Constance and returned with the master builder John of Cologne (Juan de Colonia), who completed the towers with spires of open stonework tracery.Among the most famous of the bishops of Burgos was the 15th-century scholar and historian Alphonsus a Sancta Maria.In 1919 the cathedral became the burial place of Rodrigo Díaz de Vivar ("El Cid"), and his wife Doña Jimena. On October 31, 1984, it was designated a World Heritage Site by UNESCO.
