Europe’s biggest river island
Covering an area of 9.8 km², Barthelasse Island was originally made up of a string of islets. Alluvial deposits gradually filled in the marshy areas, and major development work was undertaken to bring the various islands together. Dykes were built around the island in the 19th century to protect its banks and help it withstand flooding from the Rhône.
Barthelasse island was annexed to Avignon in 1856, and became one of the many districts of the city of the popes. Despite being less than a mile as the crow flies from the historic center of the Provençal town, it has preserved its rural and agricultural landscapes. It still helps to feed the people of Avignon.
