Bentomiz Castle, one of the largest in the province, has its origins in a Roman fortification, although its present-day architecture clearly reflects the medieval Muslim influence. Its strategic location allowed it to control the Axarquia all the way to the sea, which is the origin of the place name Bentomiz, derived from the Latin montemar.
It played a key role in the 9th century during Ibn Hafsun's revolt against the Qur'anic state and in later centuries. The castle consists of two main areas: the citadel in the higher area to the north and a larger enclosure to house the population and livestock in times of danger.
