The spa and hot springs of Bath are traditionally associated with the Romans. It is true that the Romans developed the baths and built a massive complex, with temples and administrative buildings, around them. However the site dates back to the Celtic period, and the baths have been in used almost continuously since the Romans left. The spa was revitalised in the 18th century and appears on the novels of Jane Austen. Today the Roman spa is a museum but there are still places nearby where you can take the waters.
Constructed in around 70 AD as a grand bathing and socialising complex, the Roman Baths is one of the best-preserved Roman remains in the world, where 1,170,000 litres of steaming spring water, reaching 46°C, still fills the bathing site every single day.
The Roman Baths is the site of extensive ruins and an interactive museum filled with many treasures and visual snippets that transport you back to Roman times and the lives of the Aquae Sulis people. Walk on ancient pavements as the Romans did 2,000 years ago, and explore chambers historically housing changing rooms and tepid plunge pools.
In the Elizabethan era, when the city experienced a revival as a spa. The baths were improved and the city began to attract the aristocracy. In the 18th century Bath had become perhaps the most fashionable of the rapidly developing British spa towns, attracting many notable visitors such as the wealthy London bookseller Andrew Millar and his wife, who both made long visits.

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.
