In 1962, during the widening of the road Thessaloniki-Langada, in Derveni, six cist graves, a pit and a single-chamber Macedonian tomb were unearthed. These are directly associated with the ancient Mygdonian city of Lete. The revelation of the above graves, which contained a large number of offerings, was significant for the archaeological research of ancient Macedonia and enriched our knowledge about metalworking in the region.
