History, culture and heritage

Petites Roches funicular: linking Lumbin, in the Grésivaudan area, to Saint-Hilaire-du-Touvet, in Chartreuse, the funicular is one of the oldest tourist railways (1924) and the steepest (83% under the tunnel). During the dizzying ascent, passengers are treated to a magnificent view, notably of Belledonne, the Chartreuse, the Bauges, and a nearby waterfall. Paragliders also use the funicular to reach Saint-Hilaire-du-Touvet, a free-flight Mecca. The highlight of the year is in September when the Coupe Icare and international free-flight film festival takes place. The event celebrated its 40th anniversary in 2013, when over 10,000 pilots from all continents offered an aerial and poetic performance to the 80,000 spectators come to watch flying humans.

Fort Barraux: sentinel of the Grésivaudan, the fort is one of the most prestigious strongholds in the Alpes. Built in 1597 on French territory by Ercole Negro, for the Duke of Savoy, it was taken in 1598 by Constable Lesdiguières for King Henry IV, then redesigned by Vauban at the end of the 17th century. Owned by the commune of Barraux since 1988, it is now a listed historical monument as a well-preserved example of bastion architecture.

Château du Touvet: this fortress surrounded by towers and moats in the Middle Ages, became a castle for pleasure in the 18th century when it was embellished with remarkable interior decorations. It has splendid gardens, designed in the 18th century, with a water staircase fed by the waters of the Chartreuse, ponds, fountains and ponds. The same family have been living here for 500 hundred years, but the castle is open to visitors.

La Tourne mill: also in the Grésivaudan area, in Les Marches district, the mill is close to the route. Visit the mill to learn about the history of paper with all the stages of traditional production that are still used here today, and the development of more modern printing systems.
