Secinaro, in the province of L'Aquila, is the location of what is probably the first meteoric impact crater discovered in Italy, dating to the fourth or fifth century. The town's mayor has established a “National Golden Meteorite Prize” for amateur astronomers who have conducted research on the solar system's minor bodies.Naming citation (20051215/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
