The walls of Avignon surround the city of Avignon in the south of France. They were built in the 14th century during the Avignon papacy and have been continually rebuilt and repaired throughout their subsequent history.
The current walls replaced an earlier double set of defensive walls that had been completed in the first two decades of the 13th century. During the Albigensian Crusade the town sided with the Count of Toulouse, Raymond VII but in 1226, after a three-month siege by Louis VIII of France, Avignon capitulated and was forced to dismantle the early walls and fill in the moats. Beginning in around 1231, the defences were rebuilt. Although these early walls have not survived, their path is preserved in the street plan of the city.
In 1309 Pope Clement V moved to Avignon and under the papacy the town expanded outside the limits of the earlier city walls. From the 1350s during the Hundred Years' War the town became vulnerable to pillage by marauding bands of mercenaries and in 1357 under Innocent VI, the fifth Avignon pope, work began on the construction of a new set of city walls to enclose the expanded town. The walls took nearly 20 years to complete.
The walls stretch for 4.3 km and enclose an area of 150 ha. There were originally twelve gates controlling access to the city but this number was reduced to seven when the fortifications were modified between 1481 and 1487 during the French Wars of Religion. There are now 15 vehicular entrances and 11 pedestrian entrances.
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.
