  ## Main sights
  
  * Abbey of San Pedro de Cardeña (9th-17th century)
  
  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.
  
  During the Spanish Civil War the monastery was used as a concentration camp.
  
  Since the 1940s the abbey has belonged to the Trappist order.
