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.
Collevecchio's historical importance stems from its connection to the title of Baron, which was held by the Bishop of Teramo since at least 894.
