It is not known for certain who made the mid-14th-century Golden Altar Piece. It is a masterpiece of engraving that uses Byzantine ancient enamels, which originate from the pillage of Byzantium in 1204. The Treasure of San Marco should not be missed. A large part was melted down to mint money, but what remains can satisfy the curiosity of even the most demanding visitor, from an artistic and historic point of view. It can be accessed directly from the Basilica di San Marco.
