Adria is a town and comune in the province of Rovigo in the Veneto region of northern Italy, situated between the mouths of the rivers Adige and Po. The remains of the Etruscan city of Atria or Hatria are to be found below the modern city, three to four metres below the current level. Adria and Spina were the Etruscan ports and depots for Felsina. Adria may have given its name during an early period to the Adriatic Sea, to which it was connected by channels.
