Macenas castle or watchtower is an 18th century military structure built to keep watch the coast. In 1849 it was occupied by the carabineros and after the war arrived the Civil Guard and was built an access to the castle. It was restored in the 1990’s.
On its southern side there is a dirt track which leads to the La Torre del Perulico, or Torre del Peñon tower, built during the Nasrid period (13th-15th centuries). This tower was part of a defensive system along the Mediterranean coast. The rock, the tower and the natural arch form a uniquely beautiful whole.
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.
