Fortaleza del Monte Hacho stands on a promontory 190 meters above sea level in Ceuta, occupying the entire upper portion of Monte Hacho with approximately 10 hectares and over forty circular towers. One of the world's oldest continuously active fortresses, the site traces its origins to Roman or Byzantine occupation, with confirmed Byzantine garrison presence by 534 AD. Portuguese forces captured Monte Hacho in 1415, establishing the foundations for Spanish military occupation that continues today. Declared an Asset of Cultural Interest and visible from throughout Ceuta, this monument represents centuries of Atlantic defense strategy and remains an operational military installation.
