Tiny Torcello island has few residents but it's often busy with sightseers in summer. They come to visit the Basilica di Santa Maria Assunta, with its Venetian-Byzantine mosaics and views of nearby Burano from the bell tower, or to check out the Ponte del Diavolo, a bridge with no parapets, and the stone seat known as Trono di Attila. A handful of eateries along the main canal serve lunch.
