This is the tomb of El Cid (Ruy Díaz de Vivar) and his wife Ximena in a little monastery in Old Castile called San Pedro de Cardeña:
In the graveyard outside is his horse Babieca:
They say the great battle horse died at forty and outlived El Cid by just a few months. El Cid had requested that it be buried near him in that monastery.
Now El Cid and his wife Ximena no longer lie in the old tombs above. French soldiers stole their bones during the Napoleonic invasion of Spain and took them home to France. In 1927 they were returned to Spain and buried in no less a place than the Cathedral of Burgos:
Who was El Cid?
A warrior, a nobleman, a knight, a hero. He became a legend already a few years after he died. Most Spaniards know about him because they read an epic poem in school called El Cantar de Mío Cid. It is the first great poem in the Spanish language. It was written about 1140, only about fifty years after he died.
Others know about him because of the famous movie starring Charlton Heston and Sophia Loren.
El Cid means Lord in Arabic. The Moors (North African Berbers and Saracens) gave him that name. Spaniards called him Campeador, which means something like the Fighter or Champion. He had two favorite swords. This is one:
Tizona, on display in Burgos, where it was recently bought for 1.6 million euros by the Comunidad Autónoma [State] of Castilla-Leon.
