St Mark's Basilica

In my opinion, it is the most important church in Venice, well-known worldwide, and the best representation of Byzantine art in northern Italy. It was built in 828 to be the Pantheon of the apostle Mark. It has a Greek cross and five domes on the cross, and was rebuilt after a fire in the 11th century. Although initially an austere church, has been well decorated thanksto the many donations pouring in.

Is supposed to be free but once inside if you want to see all of it is 2euro here 3 euro there, still beautiful though.
