...on the ruins of an ancient palace and it was built between 1420 and 1440.
After the death of the commissioner in 1441 and few years later the death of his son, the palace was passed from hand to hand, during which it had a lot of renewing and changing of its architecture, especially during XIX century when the architect Medusa, commissioned by the owner Trubetzkoi, heavily changed its façade and the interiors. At the end of 1800 a rich baron bought the palace in which he put all his collection of art and in 1927, after the palace was given to the Italian Republic, it became a museum.
Its façade is richly decorated, characterized by the Gothic style: the bottom part has an open gallery with five arcades and windows, and the upper part has a couple of different orders. It end with a series of spires. The material used to realize the building is white and red marble (from Verona) and the facade appears asymmetrical just because it is still unfinished.
Strange is how during the last renovation the commissioner, Franchetti, took personally care about the floor: he designed the scheme and realized a 350sq floor using various kind of marble: red marble, green, luculleo marble etc etc.
Nowadays the palace hosts the Franchetti Collection plus other art of Tiziano, Mantegna and Guardi.
