In 1970 the name was changed to Keltenmuseum and the museum was moved into the former Salt Offices (Saline Hallein) on the Pflegerplatz, which fronts the river Salzach.

In 1980 the Museum staged a major exhibition "Die Kelten in Mitteleuropa" (The Celts in Central Europe), which demonstrated the wealth of discoveries that were being made at the Hallein.

The building dates from the mid-18th century and in the Salt Office, now the top floor of the Museum, are a series of rooms, including the Prince's Chamber and Green Room, which have a series of 80 paintings by the artist Benedict Werkstötter, which illustrate the various processes of salt production.

The richest deposits of salt in central Europe are concentrated in at short distance from each other in the Eastern Alps, in the Salzburg and Salzkammergut areas.

Under the Archbishops of Salzburg during the Middle Ages, Hallein became the major centre of production in the Eastern Alps and salt routes developed up the Salzach and particularly to Bohemia.

In more recent times an excavation of a robbed burial mound in 1932 produced a spectacular bronze wine flagon.

The 'princely' warrior was buried with a wooden jug that had bronze mounts, one of which is the stylised Celtic head which is used as the logo of the Keltenmuseum.

At the feet of this warrior was his pointed bronze helmet, of typical La Tène type, an Iron sword, a bow and arrow and three lances.

There are two immediate parallels to this jug, the pair of flagons in the British Museum from a probable burial at Basse-Yutz in the French Moselle Valley.
