Alberoni is a town on the southern end of the Lido di Venezia. In medieval times, it was known as Albiola.
The lagoon was settled in Antiquity, and in the 600s, there were numerous known towns, and several important cities. Venice, however, was not one of them.
Translation of the parts related to Venice of the “De Administrando Imperio” (c.950) by Constantine VII Porphyrogenitus.
