 Collevecchio is of historical importance in that the Bishop of Teramo traditionally also carried the title, Baron of Collevecchio.The earliest known records relating to Collevecchio date back to 894 when the Bishop of Teramo, Giovanni I, was involved in a land exchange with a count from the Abruzzo region, Adelberto.The Monastery of Santa Maria, which likely fell within the territory surrounding the town, is cited in these documents.
