Venice Lagoon was inhabited from the most ancient times, but it was only during and after the fall of the Western Roman Empire that many people, coming from the Venetian mainland, settled in a number large enough to found the city of Venice.
A Lagoa de Venecia habitouse desde os tempos máis antigos, pero foi só durante e logo da caída do Imperio Romano de Occidente que moitas persoas, procedentes da parte continental de Venecia, asentáronse nun número bastante grande para fundar a cidade de Venecia.
