Starting in the 6th Century, both buried cremation urns and full body graves became common, though later only bodies were buried. The cremation ashes were buried in stone cists or pits, while bodies were buried in stone lined tombs under deck plates were made of gneiss. The dead were buried with their possessions (brooches, belts and jewelry). In the Latène era, isolated swords and helmets were added to the men's graves. The women's graves began to contain a number of amber objects, such as earrings and necklaces. Within the grave there were also containers, usually made of clay (pots, bowls, cups, cans), or occasionally bronze (Situlae or beak jugs). While these are a few imports from Etruria (8 beak jug, 1 bucket), most of the items were produced in the area. The large bronze hoard of Arbedo dates from the period around 450 BC. Over 4,000 items were discovered in Arbedo along with smelting furnaces and workshop waste. In addition to local products, there are numerous important Etruscan and northern Alpine objects.
