Spiez is a town and municipality on the shore of Lake Thun in the Bernese Oberland region of the Swiss canton of Bern.
The area between the Kander and Lake Thun in modern Spiez was home to several large Bronze and Iron Age settlements. Three separate Bronze Age cemeteries with numerous graves contained a wealth of bronze axes, knives and cloak pins from 1750 to 1500 BC. On a nearby hill, the Bürg site is slightly younger and contained knives, arrow and spear heads, a horse's bridle and a razor. The Eggli hill top was apparently a religious site during the Bronze and Iron Ages. The center of the religious site was a granite block surrounded by ash from fires and thousands of shattered ceramic fragments. The Eggli site was probably used from about 1500 until 500 BC. Celtic graves from the 4th to 2nd century BC contained gold, amber and glass ornaments which were imported from over the Alps. A rare funerary urn was buried at Faulensee during the 1st century BC.
