maintenance work undertaken in the La Cour du Pont district led to the discovery of two oak piles at a depth of 2 metres. A Carbon-14 study undertaken by the centre for chronology at the Claude Bernard University Lyon 1 (CNRS) gave a date between 39 BC and 120 AD. It is possible that they were piles for a Gallo-Roman bridge used to cross the Rhone between Les Avenières and Thuellin. From the Middle Ages to modern times In 1330 Aigline de Gerbais was married to Louis de Rivoire, knight, lord of Romagnieu, Domessin, la Bâtie-Montgascon, Villeneuve de Ciers (les Avenières), and Bruzolo en Piémont. In 1496 notes and coins prove that Humbert of Baternay was deprived of the proceeds of the sale and transfer of the lands of Dolomieu and Avenières by King Charles VIII. In October 1496 Charles VIII issued Letters Patent ceding Dolomieu and Avenieres to Humbert of Bagternay. On 22 January 1560 copies were made of letters agreed to by King Charles with René de Baternay on the subject of the lands of Ornacieux, Dolomieu, and Les Avenières. On 8 October 1609 Gabrielle de Baternay, widow of Gaspard de la Chastre, sold the lands and lordships of Avenières and Brangues as well as the Barony of Bouchage to M. of Granieu and Dorgeoise. In July 1523 letters from François I stated that the possession of the lands of Dolomieu and Avenières was held by René de Baternay. An order from the King's Council showed that René de Baternay would be restored to possession of the lands of Dolomieu and Avenières. On 15 March 1642 there was a memoir and instructions on the subject of the proceedings of the King's Council regarding the lands of Dolomieu and Avenières. 20th Century At the beginning of the 20th century the town was served two secondary railways: the Chemin de fer de l'Est de Lyon to Lyon and Aosta, and the Tramways départementaux de l'Isère, which was taken over by Tramways de l'Ouest du Dauphiné, to La Tour-du-Pin. This last operated from 1909 to 1935. Administration List of Successive Mayors Mayors from 1941 Demography In 2012 the commune had 5,487 inhabitants.
