"St. Mark's Basilica The Basilica San Marco is Venice 's crown jewel. Situated at the eastern end of Piazza San Marco, the cathedral was built around 1078 on the site of an earlier house of worship. It is famously the home of the remains of the apostle Mark, which were said to have been smuggled from the Holy Land by Crusaders in a barrel of pork. The basilica is not just a wonder from the outside; its glittering gold mosaics make it one of the most breathtaking examples of Byzantine design in the West."
