From the 1960s on, it went downhill. The mines were depleting and not profitable anymore. The last potash was extracted in Puits Théodore in 1986. Alsace's last active mine closed in 2002. Appropriately enough, it was the Amélie mine, the place where the rush for potash had begun a century earlier. Ultimately, five hundred million tons of raw ores were extracted in Alsace.

Today, a handful of mines remain. For example, the 65-metre high headframe marks the Puits Théorode, where you will also find a historic fire station building.
