Castro de Castromaior in Portomarin is one of the most popular archaeological sites in the northwest of the peninsula. In this castro, developed in the Iron Age, it was inhabited between the fourth centuries BC and first century AD until three different populations, until its abandonment with the first Roman approaches. Of him they emphasize his big dimensions, since it counts on an area of approximately 5 hectares, and his good state of conservation.
Between 2006 and 2010 it was the center of archaeological works in order to discover its entire structure, thereby achieving that in 2010 it obtained the title of Cultural Interest. Thanks to this title and being located a few meters from the route that connects the French Way with Santiago de Compostela, it has become one of the most popular locations on the Camino de Santiago.
Like other popular castros, the Castro de Castromaior is located on an elevation since its inhabitants had great visibility to be prepared for enemy attacks. It is distributed by a main enclosure, where homes were concentrated, and different walled platforms located outside. According to experts, the usual houses that formed in castro, were initially made with vegetables, but a fire calcined them and were rebuilt with stone walls. Currently, in the castro the ditches and holes where the posts were located are preserved.
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.
