Castello is the largest district of Venice. It is named after the castle that was located here during the Roman Empire. Castello is famous not only for its historical architectural monuments, which are found here in abundance, but also its gardens, which were developed there according to Napoleon’s order. Since 1895, Venetian Biennale, the International Art Exhibition, has been held in the territory of the Venetian Gardens. It is one of the most famous forums of world art.
