This palace was left unfished, but the ground floor allows us to imagine what a colossal home the Veniers had in mind to build. A wooden model of the whole palace, designed by Lorenzo Roschetti in 1749, is in the Civic Correr Museum. Behind the unfinished work lies a fine garden where tradition says the Veniers kept a lion from which the name dei Leoni may be derived. 
It is now a museum of modern art set up by the American heiress Peggy Guggenheim. It is home to important works of art from the early 20th century avantgardists.
