San Esteban de Gormaz Castle
A Moslem, Calif-style fortress built in the 10th
century to defend the lands of the Duero from Christian attacks
during the Reconquest.
It´s divided into two areas by a moat: the fortress and the walled enclosure where the soldiers and the cisterns were. In the fortress there were seven towers out of which the Almanzor and the Keep are the most interesting. It also had an underground reservoir and an important armoury.
The Gormaz castle is mentioned in the "Cantar de Mío Cid". El Cid Campeador was mayor of the fortress once taken by the Christians. It is the longest fortification in Europe.
