The Cathedral, dating back to 1038, is dedicated to Saint Stephen the Protomartyr. It is the oldest and most important building in the city and stands in Piazza Vescovado.
The structure is characterized by a tripartite facade divided by pilasters and a central portal flanked by two bas-reliefs of Byzantine style. Inside, the Cathedral houses interesting works of art, including the Pala d’Oro, an important piece of chiseling, dating back to the 13th – 14th century, placed behind the main altar.
The work is said to have been donated to the community of Caorle by the queen of Cyprus, Caterina Cornaro, as a sign of gratitude for a survived shipwreck.
The apse at the end of the left nave contains, at the base of the tabernacle, one of the most significant Roman artifacts: a funerary altar belonging to the Licovi family, dating back to around the 1st century a.d.
