Castillo de Guzmán el Bueno
The Castillo de Guzmán el Bueno (Castle of Guzman el Bueno) in Tarifa was built in the middle of the 10th century by order of Caliph Abd al-Rahman III.
Its strategic position had been used by earlier buildings, such as the remains of roman structures, which can be found inside. Its mission, predominantly military, has remained so until today.
This fortress had a very important role during the reconquest, the defense of attacks by Barbary Pirates in centuries after and the War of Independence.
