The story that haunts this land

The Keltenmuseum Hallein houses central Austria's largest collection of Celtic artifacts, witnesses to 6th century BC princely tombs discovered on Dürrnberg. This neoclassical facade hides treasures of Celtic warriors who controlled salt trade routes between the Adriatic and Baltic seas. The exhibited gold fibulae, torcs and ritual helmets reveal a refined civilization, masters of metallurgy and long-distance commerce, well before Romans arrived in the Alps.

The Dürrnberg plateau has dominated Hallein for 2600 years, its underground galleries carved by Celtic miners from the 7th century BC. These tunnels, among Europe's oldest, fed a commercial network extending to Mediterranean coasts. Dürrnberg's Celtic princes accumulated considerable wealth through this salt monopoly, a commodity as precious as gold at the time. Their burials reveal objects from Greece, Etruria and Baltic amber, proof of intercontinental exchanges.

Hallein's Altstadt preserves the medieval layout of this Salzburg town, its cobbled alleys winding between 17th-century baroque facades. This post-Renaissance architecture masks older foundations, where Celtic descendants continued mining under Roman then Bavarian rule. The Rathaus, rebuilt after the 1843 fire, stands at the heart of this compact historic center you cross following clues of your Celtic investigation.

Griestorgasse and Griesbrücke connect the historic Gries district to downtown via a bridge over the Salzach, this river that once carried salt barges toward the Danube. These medieval cobbled alleys saw convoys of Venetian, Bavarian and Hungarian merchants coming to supply themselves at Hallein's warehouses. Pernerinsel island, a cultural space on the Salzach, offers the final viewpoint over this salt city that enriched Salzburg's archbishopric for centuries.

Your Hallein route reveals 2600 years of continuous Alpine salt exploitation, from Dürrnberg's Celtic princes to the archbishopric's baroque merchants. This interactive investigation lets you grasp the geographic permanence of natural wealth, shaping civilizations far beyond political conquests. You leave with visceral understanding of this unknown Celtic Austria, predating Mozart and the Habsburgs, where mines' white gold already created princely fortunes.
