The frontier

The most important event in the castle’s history took place in 1264, when Alfonso X the Wise incorporated the town into the Kingdom of Castile during the Reconquest.

In view of the importance of the zone and its frontier location, Alfonso X transformed the existing mosque by building a fortress-church over it.
In the 13th century the fortress stood on the bank of the River Guadalete, from which it controlled the entire Bay of Cádiz, with the moat and the river giving it natural protection. Moreover, the commercial boats could practically reach the gates of the Castle because the river was navigable.

The Castle of San Marcos offers its visitors various settings and decorations. Inside, the predominant styles are Almohad and Gothic, while outside it maintains a rather more pictorial decoration characteristic of old castles.
