The Gallo-Roman amphitheater in Grand, Vosges, was one of the largest amphitheaters in the Roman Empire with 17,000 seats. Located on the outskirts of the town, the amphitheater was built outside the ramparts of Grand in the 1st century AD. The builders of the day took advantage of the natural slopes of the valley when constructing this semi-elliptical theater. We were able to have a real sense of what the Grand Amphitheater looked like originally as the seating has been constructed over one-half of the original stone supports. The seating has been built to the original dimensions and height so that you have a real sn understanding of the size of the amphitheater.
The amphitheater was built in the was abandoned in the 4th century with the rise of Christianity. The inhabitants of Grand then used the amphitheater as a quarry and for years to come they removed many of the structure’s stones to use for other purposes.
There was also an important sanctuary dedicated to Apollo Grannus, the god of healing. You can still see the remains of the rampart that surrounded the sacred enclosure.
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.
