The University Museum A Domus do Mitreo is a museum center built on the old site of the Pazo de Montenegro and annexed buildings, next to the Roman walls of Lugo. The Museum is called Domus do Mitreo because when archaeological surveys were carried out, prior to the construction of the new building, the remains of a domus appeared. This domus, during the Lower Roman Empire, was partially reformed to build a private building intended for use as a Mithraeum. The historical importance of the archaeological remains discovered led to revise the architectural project initially planned to preserve and incorporate them into the new building.
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.
