What was once one of the major Venice scuolas is now an important sight. Its beautiful exterior decorated with many delicate statues is equally impressive as the interior where you can find several paintings by popular Venetian artist - Tintoretto. It used to be a hospital and now you can find an interesting museum of medicine inside.
