The Caerleon Roman Fortress and Baths museum is a historical site located in the town of Caerleon. Roman Wales was the farthest point west that the Roman Empire in Roman Britain extended to, and as a defence point, the fortress at Caerleon built in AD 75 was one of only three permanent Roman Legionary fortresses in Roman Britain. It was occupied and operational for just over 200 years.
The site of the baths was excavated in the late 1970s, and a curator was appointed in 1980 when the site was opened to the public.
The Roman Baths Museum lies inside what remains of the fortress of Isca Augusta close to the National Roman Legion Museum. The baths museum has a covered walkway over part of the remains of the military bath house. There was a frigidarium, tepidarium and caldarium, as well as an open-air swimming pool.
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.
