Queen Jeanne, born in Naples in 1326 and assassinated in 1382 by her cousin Charles of Anjou, had a very eventful life and four husbands! She left a marked impression in Provence, where she came only twice in her forty years of reign. Often impoverished and needing financial aid, she granted rights in favourable and advantageous ways, which perhaps explains her popularity.

Tradition has it that, while staying in Salignac in 1379, she gave birth to an illegitimate child. This child was hidden in Saint-Symphorien, where she bought the discretion of the inhabitants by relieving them of certain royal duties and obligations, as well as financing the construction of a bridge over the Vançon river.

The Bridge of Queen Jeanne, a listed monument in 1977, is 35m long and only 2m wide. Its humpback shape continues the tradition of medieval bridges even though it probably dates from the 17th century.

The arch has an opening of 22m and a height of 12.5m.
Saint-Symphorien, uninhabited in 1471, had 213 inhabitants in 1836 and 6 in 1968. Joined to Entrepierres in 1973, it is now deserted.
