The Castillo de Santa Ana in Roquetas de Mar represents centuries of coastal defense evolution, with its origins traced to an early 14th-century Nazrid fortification built as part of al-Andalus's maritime defense system. Substantially rebuilt and expanded between 1501 and 1522, the fortress was ravaged by an 1804 earthquake, leaving only its distinctive square-shaped armoury standing today. Now functioning as an art and cultural center located on Bajadilla Beach near the lighthouse and port, the castle's thick stone walls and panoramic views of the Mediterranean offer visitors a tangible connection to the region's strategic maritime history.
