Joux Castle

Highlight • Castle

The castle of Joux also called Fort de Joux, perched on its rocky outcrop and located near the Swiss border served both as a place of observation and defense but also had the function of being a prison. Its most famous occupant who died in his jails is the Haitian independentist and revolutionary Toussaint Louverture. Napoleon having re-established slavery for pecuniary reasons, he opposed the emperor, which resulted in his imprisonment. You can visit this fort.

Joux Castle

Highlight • Castle

The Château de Joux (or Fort de Joux) is a fortified castle near Pontarlier, in Franche-Comté, in the French Jura.

The castle is located at a strategically important location above the small town of La Cluse-et-Mijoux. The Dijon-Lausanne trade route crossed the Jura mountains here. The road crosses a rocky cliff and could therefore be easily controlled from the castle.

View of the Château de Joux

Highlight • Castle

This is a spectacular fort standing high on a rocky spur. Worth a short detour for a visit if you are into your history. Initially built in wood in the 11th century, it was then rebuilt in stone in the 12th century. It has been a medieval castle, a border fortress, a state prison and then an artillery fort.

View of Fort de Joux

Highlight • Other

Overlooking the cluse de Pontarlier, the Fort de Joux is listed as a historical monument. Closed during the winter period, it opens every spring.

From here, you have a beautiful view of the fort, to better observe how it blends into a green setting. Also a colony of chamois has taken up residence in the foothills and this belvedere allows you to observe them well.
