Fort de Joux Audio Guide for La Cluse-et-Mijoux

Welcome to the Fort de Joux, a sentinel carved into the Jura mountains that has guarded the pass between France and Switzerland for over one thousand years. As you stand here in La Cluse-et-Mijoux, take a moment to look at the sheer rock promontory and the cliffs that rise one hundred meters above the valley floor. This strategic bottleneck, known as the Cluse de Pontarlier, has been a vital trade and military route since the Roman era, linking northern Europe to the Mediterranean. What you see today is not just a building, but a massive stone record of European history, stretching from a simple eleventh-century wooden outpost to a modern defensive fort integrated into the Maginot Line. You are walking through a site that has been besieged countless times and owned by medieval lords, the Dukes of Burgundy, the Spanish Hapsburgs, and the kings of France. Prepare to explore five rings of fortifications, three drawbridges, and a labyrinth of over two hundred and fifty rooms as we peel back the layers of this mountain titan.
