Vouglans Dam

Highlight • Lake

Built in 1968, the Vouglans dam is the source of the 3rd largest water reservoir in France in terms of its volumetric capacity after the Serre-Ponçon and Sainte-Croix lakes. The emerald color of the lake water is of natural origin. It would be due to the presence of calcite grains attaching to the phytoplankton.

Arinthod

Highlight • Settlement

Located in the heart of the Petite Montagne, the village of Arinthod reveals beautiful architecture. Its triangular square lined with arcades and decorated with a fountain dates from 1750. The atmosphere is pleasant, especially on Saturday morning, market day.

Pont de Thoirette

Highlight • Other

The bridge separates two departments, the Jura and the Ain.

"Iron bridge. For several centuries, the Ain was crossed at Thoirette using a ferry, called Christouphe's ferry, named after the commune where the passenger resided.

From 1808 to 1811, the riparian communes contributed to building a bridge in place of this ferry.

The project had been drawn up by Mr. Cordier, from Orgelet, an engineer then in charge of directing the works for the Simplon road.

Various obstacles opposed the execution of this work.

It was not until 1829 that an iron bridge was built, which collapsed in 1843.

The Ain department has just replaced it with an iron bridge currently open to traffic".
