Palazzo Pezzoli houses the collection of the art-obsessed collector Gian Giacomo Poldi Pezzoli, who, before his death in 1879, arranged for his palace to remain unchanged and to be opened to the public. You can now stroll through different epochs of art history, represented by valuable paintings by Botticelli, Piero della Francesca, Mantegna, and Canaletto. Exhibitions also include fine porcelain, furniture, clocks, and weapons.
