The Saint Bénezet bridge, a major witness of the history of Avignon, is known throughout the world thanks to the famous song. Built from the 12th century, it was washed away several times by the floods of the Rhone, and finally abandoned in the seventeenth century. Classified World Heritage by UNESCO.
