Overlooking the Salzach, the glass-fronted Keltenmuseum runs chronologically through the region's heritage in a series of beautiful vaulted rooms. It begins with Celtic artefacts, including Asterix-style helmets, an impressively reconstructed chariot and a selection of bronze brooches, pendants and buckles. The 1st floor traces the history of salt extraction in Hallein, featuring high points such as a miniature slide and the mummified Mannes im Salz (man in salt) unearthed in 1577. There is a pamphlet with English explanations (€2.50).
