Bentomiz Castle is an ancient Moorish fortress built on a hill near the village of Arenas in the province of Málaga. It sits at a height of 711 metres, and lies to the northeast of Vélez-Málaga.
The castle site is thought to have been occupied by the Phoenicians, Greeks and Romans, although it is not clear which parts of the ruins date to which period. Roman baths have been found there. The Arabs built on the existing structure. The fortress, then called Munt Mās, was mentioned in the memoirs of Abdallah ibn Buluggin, ruler of the Taifa of Granada in the eleventh century. He described it as a formidable stronghold. The fortress surrendered to him during a civil war that he fought with his brother.
When Ferdinand II of Aragon reached the area en route to Vélez-Málaga, in the campaign that culminated in the Siege of Málaga (1487), the Granadan Sultan El Zagal brought a force to oppose them which he stationed around the Bentomiz castle. The Moors attacked the Christian siege train during the night of 25 April 1487 but were repulsed, and in panic retreated towards Granada. The castle was taken over by the Catholic Monarchs in 1487 and maintained as a defensive post. The castle is now ruined, but there are still towers, walls and underground chambers.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
