The fort of Guadalupe is one of the most beautiful in Hondarribia. Its strategic location required a strong fortification for the village, and not only in the old part because the wall extends, in the form of multiple forts, to the whole village.
The fort's construction began in 1890 and opened 10 years later. It was used as a prison during the Civil War and as a military barracks till the end of the eighties. Nowadays, guided visits are organized at the weeekends in summer time.
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.
