Castillo de Aguilar is known from at least the 9th century. It is mostly in ruin, a part turned into a cistern for the local aqueduct. In the 9th century Aguilar de la Frontera became the headquarters of the rebel Umar ibn Hafsun, who built extensive fortifications and reinforced the castle. However, in 891, Umar ibn Hafsun lost the town to emir Abdallah ibn Muhammad of Córdoba. Due to its strategic position, it was contested and, after the dissolution of the caliphate of Córdoba, it became part of the cora of Cabra.
In 1240 it was conquered by the Christians, although numerous Muslims were allowed to remain. King Peter I of Castile assigned its seigniory to Alfonso Fernandez Coronel, but later reannexed it to the crown. The town was renamed Aguilar of the Frontier due to its position on the border with the Moorish Kingdom of Granada.
Since the mid-seventeenth century the castle was no longer needed for defense, consequently in 1860 it was converted into a Hospital. The Lisbon earthquake in 1755 caused part of the building to collapse. The fallen stones were reused for various public and private works. The remains of the castle are located on the hill to the north of the town on the extension of Calle Villa. The Tourist office is located at the castle. Free guided tours available on request.

The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
