Because salt was one of the most important medieval commodities, Salzburg grew powerful and rich through salt mining. However, in post-war Austria traditional production facilities were no longer able to meet the requirements of a globalized economy and many salt mines were forced to close. The Hallein mine near Salzburg was shut down in 1989. Since its closure, former mine workers are still granted 56 kg of free salt per year.
56 kg of industrially-manufactured salt licking stones are stacked on top of each other and are slowly dissolved by a dripping bottle of Tequila, tracing the desired transformation from an industrial to a cultural city.
