When you step on the stones of this museum site, the O Castro de Vigo. A Orixe da cidade, you’ll discover where the first inhabitants of Vigo lived.
The Castro is a 1 mile² archaeological site that includes the reconstruction of three castreño buildings pertaining to one of the largest and most evolved towns in Galicia. This small part of the Vigo oppidum shows us how people lived in castros 2,000 years ago.
The archaeological site is located on the slopes of O Castro Mountain, right in the centre of Vigo. Take the opportunity to explore its nature trails and climb to the top, where you’ll see the remains of the old walled city and enjoy the splendour of the Vigo estuary from the O Castro viewpoint.
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.
