The Saint Bénézet bridge, commonly called the bridge of Avignon outside of Avignon itself, is a bridge built between 1177 and 1185, linking the town of Avignon to the Saint-Bénézet chapel. 920 meters long, it had 22 arches and mesured 4 meters wide.
In 1226, after the terrible siege laid by Louis VIII against the city, the bridge was three quarters destroyed. A few years later, despite interdictions, the Avignonnais got down to the job and rebuilt it. Of the precedent bridge, only the chapel called the low chapel remains. Because the roadway of the second bridge was raised, the St Nicolas chapel is called the upper chapel since it was built on this new roadway.
In the 17th century, the city could no longer bear the costs of maintennce and repair. In 1603, following strong flooding of the Rhône, one arch fell down, then three others in 1605. Repair work did not start until 1628, interrupted by a plague epidemic, and the bridge was not usable until 1633. Two months later, two more arches were swept away by the Rhône. At that time, diverse means were used to cross the river. An island, today called Ile de la Barthelasse, formd in the middle of th river bed. People left from the Philippe le Bel tower, situated in Villeneuve-lés-Avignon in the French kingdom (on the right bank of the Rhône), crossing to the island by ferry. They then crossed the island on foot following a path which led, by way of wooden stairs, to the bridge's 4 remaining arches to finally reach the city of Avignon.
