While waiting for our ferry departing for Cadiz, we had a chance to visit a local fair in El Puerto de Santa Maria). I made some interesting photography here. One of the first tourism objects I noticed in El Puerto was Castle of San Marcos.
Castle of San Marcos (also Castillo de Alfonso X El Sabio) is a medieval castle located in El Puerto de Santa María, Cádiz, Spain. The castle was erected as a fortified church by King Alfonso X of Castile. It was built on the site of a mosque of which the wall of the qibla survives.

The castle was declared a national monument on 30 August 1920 and is currently listed in the Spanish heritage register as a Bien de Interés Cultural.

Alfonso X (also occasionally Alphonso X, Alphonse X, or Alfons X,23 November 1221 – 4 April 1284), called the Wise(Spanish: el Sabio), was the King of Castile, León and Galicia from 30 May 1252 until his death. During the Imperial election of 1257, a dissident faction chose him to be King of the Romans (Latin: Rex Romanorum; German: Römisch-deutscher König) on 1 April. He renounced his imperial claim in 1275, and in creating an alliance with England in 1254, his claim on Gascony as well.
