The castle consists of a wall with five towers. There is a first access gate to the main entrance, before the walled area, which is a semicircular arched gateway that supported a double-leaf gate. In front of the gate there is a round mark associated with the footprint of James I's horse, according to legend.

After a few steps, there is a second doorway protected by a stone wall with three loopholes or arrow slits oriented to protect the entrance.

Then, after a few more steps, we find the first crenellated tower, the keep, popularly known as the "constipador". It is the central structure of the castle that served as the lord's residence.

Around it are the walls, ruins of Gothic architecture from the 14th century. To the right is an esplanade with the remains of a cistern and around it a wall with battlements. Next to the cistern is a second defensive tower known as the "Torre de Migjorn" (western tower), which consists of a large wall with loopholes in the tower itself.

The so-called "prison of the Moors" is a square building crowned by a tower protected by loopholes, located to the south and which served as a watchtower for this part of the castle, with the main wall facing Mecca. It is also known as "Torre de sa Cova" due to its proximity to a nearby cave.

Among other constructions, there are also several cisterns, coal bunkers and lime kilns.
