San Pedro de Cardeña main façade.
This abbey was the burial place of El Cid, the 11th century warrior, his wife Jimena Díaz and, supposedly, his horse Babieca.
The remains were removed during the Napoleonic Wars when occupying troops ransacked tombs looking for treasure. El Cid and his wife were reburied in Burgos.
