The Roman walls of Astorga were built at the end of the 3rd century AD or beginning of the next century. The reasons that caused its construction are related to a period of instability experienced in the last years of the Roman Empire, especially originated by the incursions of the barbarian towns from the center of Europe. The walls has a length of 2,2 km.
At the end of the thirteenth century, repairs were documented by the hand of Bishop Nuño, who is credited with an important building task in the city of Astorga. However, we do not know the scope of these contributions, which may have significantly altered the appearance of Roman fortification.
