The archaeological remains found near the Águila Castle seem to confirm the presence of a pre-islamic population, maybe from the Roman Age.
Apparently in 914 the inhabitants of the fort looked like emirales troops burned the city of Algeciras ships that supported the revolt on Ibn Umar Hafsun, in any case the construction of the castle had to be early to be this hard hit area by Berber rebellions and Mozarabic.
The castle was restored in 1839 after it was conquered by French army in 1810. It was however badly damaged in the explosion in 1842.
The Águila Castle is the most representative monument in Gaucin, from the fortress you can see stunning views, in a clear day you can even see the North of Africa.
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.
