The Obélisque d'Arles is a 4th-century Roman obelisk, erected in the center of the Place de la République, in front of the town hall of Arles. The obelisk is made of granite from Asia Minor. It does not feature any inscription. Its height together with its pedestal is approximately 20 m.
The obelisk was first erected under the Roman emperor Constantine II in the center of the spina of the Roman circus of Arles. After the circus was abandoned in the 6th century, the obelisk fell down and was broken in two parts. It was rediscovered in the 14th century and re-erected on top of a pedestal soon surmounted by a bronze globe and sun on March 26, 1676.
Designed by Jacques Peytret, these ornaments changed in times of political regimes. During the Revolution, the sun was replaced by a Phrygian cap; under the Empire, the eagle replaced the cap; under Louis-Philippe, the royal sun took the place of the rooster hunting the eagle. Since 1866, the ornaments were permanently removed and replaced by a bronze capstone until a fountain and the sculptures around it were designed by Antoine Laurent Dantan in the 19th century.
This obelisk It is part of a 1981-designated UNESCO world heritage site, the Arles, Roman and Romanesque Monuments.

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.
