Torre de las Bóvedas is a coastal watchtower built between 1571 and 1575 near Marbella, forming part of a defensive network warning against pirate and Moorish incursions. The tower features a distinctive circular frustoconical shape with a diameter of 8.20 meters at the base and stands over 10 meters tall, topped with machicolations for stone projection. Located 400 meters inland and adjacent to the Las Bóvedas Roman baths from which it takes its name, it remains one of Marbella's best-preserved coastal defenses and has held protected status (BIC Level 1) since 1985.
