Exactly 500 years ago, Bohemia came under Habsburg rule through a strategic marriage alliance. This immediately expanded the market for Hallstatt salt, fueling the growth of the Salzkammergut salt industry in the following decades. The scale of salt mining as we know it today developed as a result of this market expansion, including the opening of the Ischl saltworks, the construction of the brine pipeline, and the rise of Ebensee.
