The Mattador Cultural Association (Associazione Culturale Mattador) was established in Trieste on 28 July 2009 with the aim of organizing and carrying on the Mattador International Screenplay Award dedicated to Matteo Caenazzo from Trieste. Matteo graduated in pictorial decoration at the Nordio Art School of his city and was a student at the Ca'Foscari University of Venice.

The archaeological remains from researched settlements reveal what a late prehistoric home was like, what the interiors of houses looked like, and which activities were practised in them. There are many known settlements from the Early Iron Age (9th-4th century BC) in the vast area shaped by the flow of the Soča River and its tributaries, but most of them are poorly researched. One exception is the settlement in Most na Soči, where more than 30 houses have been discovered.
