in the district of Castelletto sopra Ticino (Via del Maneggio, Via Aronco, Via Repubblica) the oldest aristocratic necropolis of Piedmont, developed between the end of the ninth and seventh centuries BC. It turned around 670 BC in an area of dynastic cult of the first proto-urban center of Piedmont. Of the 44 graves identified in the excavations, 33 were still almost intact. After a long activity of cataloging and restoration, the artifacts (urns and grave goods) were exhibited between 2009 and 2010 at the multipurpose room Albino Calletti of Castelletto sopra Ticino in a major exhibition entitled L’alba della città - Le prime necropoli del centro protourbano di Castelletto Ticino.

Golasecca I B: late 8th - early 7th century BC. Golasecca I C: 7th century BC. Golasecca II A: 600-550 BC. Golasecca II B: 550-500 BC. Golasecca III A: 500-350 BC. G. III A 1: 500-450 BC. G. III A 2: 450-400 BC. G. III A 3: 400-350 BC. History Sites characteristic of Golasecca culture have been identified in western Lombardy, eastern Piedmont, the Canton Ticino and Val Mesolcina, in a territory stretching north of the Po River to sub-alpine zones, between the course of the Serio to the east and the Sesia to the west. The site of Golasecca, where the Ticino exits from Lake Maggiore, flourished from particularly favorable geographical circumstances as it was quite suitable for long-distance exchanges, in which Golaseccans acted as intermediaries between Etruscans and the Halstatt culture of Austria, on the all-important trade in salt. The commercial mediation then broadened to include the Greek world, bringing in oil and wine, bronze objects, Attic pottery, incense and coral, and northwards the more distant transalpine world, sources of tin for bronze and amber from the Baltic Sea. In a broader context, the subalpine Golasecca culture is the very last expression of the Middle European Urnfield culture of the European Bronze Age. The culture's richest flowering was Golasecca II, in the first half of the 6th to early 5th centuries BC. It lasted until it was overwhelmed by the Gaulish Celts in the 4th century BC and was finally incorporated
