The walls of Avignon are a series of defensive stone walls that 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.
