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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
