The castillo de Santa Ana, also known as Castillo de Las Roquetas, is a fortification built between the 16th and 17th centuries, located in the town of Roquetas de Mar which was used for refugee to the inhabitants who lived near the port. It has an oblong shape. Near the castle there is a lighthouse.
The 1804 earthquake destroyed most of the structure, and only survived one of the towers and the raised level area, which has been conserved and recovered.
