Torcello is one of the smallest islands in Venice, and is near Burano. It is estimated that approximately 20 inhabitants remain, from the original 20,000.
As you get off the water taxi, you walk up a narrow, brick paved path towards the the main square. To your right is the canal, and to the left are a couple of restaurants and some shops. You will see the famous "Ponte del Diavolo" (the Devils' bridge), which is one of only two bridges without railing.
At the end of the island are 2 churches which are the only ones left. In the Cathedral Santa Maria Dell'Assunta, are many Bizantine mosaics from the 11th to the 13th century. The most famous is the "Last Judgement". You are not allowed to take photos or videos as this helps preserve them.
Next to the cathedral is the 11th century church of Santa Maria Fosca, surrounded by a 5-sided portico in the shape of a Greek cross. This was being renovated while I was there, so I did not get a chance to see it.
Outside both churches and surrounded by a fence are many statues and artifacts which were found when they were excavating.
Across from the Cathedral in a 14th century mansion is a very interesting museum.
