The castle stands on a prominent rocky ridge above the village. The fortress, although the ramparts are reminiscent of Moorish castles, was built by the Christian king of Castile, Sancho IV in the thirteenth century replacing a much smaller fortress which had been built earlier by the Muslim rulers of Andalucía. The Muslim structure is thought to have been built on top a much early Roman fortification. The castle was part of a defence system built to protect the city of Seville from the Portuguese. This defence system was called the Banda Gallega or The Galician Band. The system composed of three lines of defence, which mostly utilized older Moorish fortresses. The first line contained the castles of Aroche, Encinasola and Fregenal de la Sierra. In the second line was the Torre of San Bartolomé and Cortegana castle. The third line included Santa Olalla del Cala and the fortress at Aracena.

The castle is constructed from stone masonry and brickwork. The curtain walls have ten towers in total. Four of the towers are circular and the other six are rectangular in shape. The towers are constructed of solid stone and rise to the height of the parapet at which there is a vaulted chamber. This is topped by battlements of which some have pyramidal and brick cube castellation. The inner precinct is of an irregular coffin shape and follows the plan of the ridge top of the hill. On the North West elevation there is an entrance tower which is turned 90° to the main curtain wall of the fortress.

Following the castle’s decline as a fortress other uses were found for the stronghold. In the 19th century and into the 20th century the castle precinct and curtain walls were used as the municipal cemetery. The walls were pierced to form burial niches. This had a detrimental effect on the castle, considerably weakening the structure. In 1949 the castle was declared a site of cultural interest and measures were taken to preserve the site.

The church of Nuestra Senora de la Asuncion stands at the southern end of the rocky hill were the castle is situated. The church you see today has had different uses in since it was first built in the 9th century. In the 10th century it was a synagogue and was the Jewish quarter of the village. Two columns from that period can be seen inside the church. During the period of Muslim occupation the building became a mosque. The Apse still retains it Mudejar style with its brick arches and vaults. Two noted features of the Christian church include a fine example of a Gothic doorway, and a statue of the Virgin de los Dolores carved by the Spanish Baroque sculptor Juan de Mesa y Velasco of Seville. Unusually, there is also a preserved ship's anchor, kept here to commemorate the time when Santa Olalla was the base to a Maritime infantry regiment during the Napoleonic wars.

Opposite the doorway to the Iglesia de Nuestra Senora de la Asuncion, and a little down the hill, stands a 16th Century Plateresco style cross erected to mark the way of Pilgrimage known as the 'Silver Way' or Vía de la Plata to Santiago de Compostela from the Andulucian city of Seville. The marker consists of a baluster column topped by a Genovese capital. Above the capital sits a Plateresque flint cross.
