Santa Fosca, Romanesque church in Torcello, Italy.

Santa Fosca is a Venetian-Byzantine church on Torcello in the Venice Lagoon, rebuilt around the 12th century to house the relics of Saints Fosca and Maura. Its exterior is surrounded on five sides by a portico with raised columns and Byzantine capitals, while the interior follows a Greek cross plan with three naves and apses beneath a circular dome.

The church was first built before the 9th century and then largely rebuilt during the 11th and 12th centuries. It was during that later phase that it took on its current form, with the portico and the Greek cross layout that still define it today.

Santa Fosca stands right next to the Cathedral of Torcello, forming one of the oldest sacred areas in the lagoon. Visitors can walk freely inside and take in the plain interior, which has almost no decoration but a strong sense of stillness.

Torcello is reached by vaporetto from Venice, and the ride crosses open stretches of the lagoon, so it takes a fair amount of time. The church is only a short walk from the landing stage, so the whole visit can easily be done on foot.

The church was rebuilt around the 12th century to hold the relics of Saints Fosca and Maura, brought from Sabratha in Africa. Its five-sided portico is carried on columns with raised bases and Byzantine capitals, and the interior follows a Greek cross with three naves and apses beneath a circular dome.
