The National Museum of Roman Art is an archaeology museum located in Mérida. Devoted to Roman art, it exhibits extensive material from the archaeological ensemble of Mérida (the Roman colony of Augusta Emerita), one of the largest and most extensive archaeological sites in Spain, registered as UNESCO World Heritage Site in 1993.
An archaeology museum in Mérida was created for the first time through a royal order issued on 26 March 1838. On the occasion of the two thousandth anniversary of the city's foundation, the museum was refounded as the National Museum of Roman Art in 1975. The current building is a work by Spanish architect Rafael Moneo. Building works started in 1981. The new premises were unveiled on 19 September 1986.
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.
