Built between 1748 and 1772 by Giorgio Massari for a Bolognese family, this palace is one of the last of the great noble residences on the Grand Canal. Once owned by auto magnate Giovanni Agnelli, it was bought by French businessman François Pinaut in 2005 to showcase his highly important collection of modern and contemporary art (which has now grown so large that Pinaut rented the Punta della Dogana, at the entryway to the Grand Canal, for his newest acquisitions). Pinaut
brought in Japanese architect Tadao Ando to remodel the Grassi's interior. Check online for a schedule of temporary art exhibitions.
