Torre del Barranc d'Aigües (Torre de Lloma de Reixes) is a 16th-century defensive tower on Playa Llomes de Reixes in El Campello, built to guard the Valencian coast against Berber pirate raids. Constructed in the second half of the 1500s as part of a broader coastal watchtower system, the tower occupies a site with deeper historical significance: it once marked the border between Castile and Aragon until King James II annexed these territories to Valencia in 1296. Though partially deteriorated, the upper structure remains visible enough to reveal its military design and construction methods. The tower stands within a protected natural landscape of considerable beauty.
