Torcello is a sparsely populated island at the northern end of the Venetian Lagoon, in north-eastern Italy. It was first settled in 452 CE and has been referred to as the parent island from which Venice was populated. It was a town with a cathedral and bishops before St Mark's Basilica was built.

The Venetian Lagoon is an enclosed bay of the Adriatic Sea, in northern Italy, in which the city of Venice is situated. Its name in the Italian and Venetian languages, Laguna Veneta—cognate of Latin lacus, "lake"—has provided the English name for an enclosed, shallow embayment of salt water, a lagoon.
