Drevant Gallo-Roman site dates from the 1st to 3rd centuries and includes a well-preserved theater, a sanctuary, two bath complexes, and residential areas. It was a secondary settlement connected to river navigation and a local road. By the 4th century, the site abandoned, and the theater became a craft workshop. In the Middle Ages, the ruins were used as a stone quarry.
The structure combines elements of both an amphitheater and a theater, with an 85m-wide cavea supported by buttresses. The 27m-diameter arena, enclosed by a 2.6m-high podium wall, suggests it was used for circus performances.
Initially mistaken for a forum, the sanctuary features a large enclosure (116 × 89m) with a small central temple (fanum). Over time, it was expanded with monumental entrances, an octagonal sacred structure (possibly a bidental), and surrounding buildings.
Discovered in 1835, the two bathhouses (35 × 29m and 42 × 33m) had typical Roman features, including heated rooms. They were likely supplied by an aqueduct sourcing water 5 km away.
Developed in the late 1st or 2nd century, housing blocks were found mainly north of the site. Some residences included baths, while others may have served as inns or worker lodgings. Abandonment began in the mid-3rd century.
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.
