Torcello

Torcello (; ) is a sparsely populated island at the northern end of the Venetian Lagoon, in north-eastern Italy. It was first settled in 452 AD 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.

==History== After the downfall of the Western Roman Empire, Torcello was one of the first lagoon islands to be successively populated by those Veneti who fled the terra ferma (mainland) to take shelter from the recurring barbarian invasions, especially after Attila the Hun had destroyed the city of Altinum and all of the surrounding settlements in 452. Although the hard-fought Veneto region formally belonged to the Byzantine Exarchate of Ravenna since the end of the Gothic War, it remained unsafe on account of frequent Gothic (Sarmatian) invasions and wars: during the following 200 years the Lombards and the Franks fuelled a permanent influx of sophisticated urban refugees to the island’s relative safety, including the Bishop of Altino himself. In 638, Torcello became the bishop’s official seat for more than a thousand years and the people of Altinum brought with them the relics of Saint Heliodorus, now the patron saint of the island.
