A site on Lake Hallstatt in the Austrian Alps with a cemetery of over 3000 cremation and inhumation graves with great quantities of local and imported grave goods. There were prehistoric salt mines in the area. Hallstatt is also a late Bronze age and early Iron Age cultural tradition, c 1200-6000 BC in continental temperate Europe. The term also refers to a cultural period of the Late Bronze Age and Early Iron Age in central Europe, divided into four phases, Hallstatt A, B, C, and D. In central European archaeology the terms Hallstatt A (12th and 11th centuries BC) and Hallstatt B (10th-8th centuries BC) are used as a chronological framework for the urnfield cultures of the Late Bronze Age. The first iron objects north of the Alps appear at the close of this period, and the Iron Age proper begins with the Hallstatt C (or I) stage of the 7th century BC. The area of fullest development is Bohemia, upper Austria and Bavaria, where hillforts were constructed and the dead were sometimes interred on or with a four-wheeled wagon, covered by a mortuary house below a barrow. Sheet bronze was still used for armor, vessels, and decorative metalwork, but the characteristic weapon was a long iron sword (or bronze copy). These swords are found as far afield as southeast England, in the so-called 'Iron Age A' cultures. During the Hallstatt D (or II) period, in the 6th century, the most advanced cultures are found further west, in Burgundy, Switzerland, and the Rhineland. Wagon burials are still prominent and trade brought luxury objects from the Greek and Etruscan cities around the Mediterranean. By the close of this period in the mid-5th century BC, elements of Hallstatt culture are found from southern France to Yugoslavia and Czechoslovakia. The Hallstatt precedes the La Tène period; the Hallstatt Iron Age culture certainly developed out of the Urnfield Bronze Age groups.
