Museo Paleontologico Territoriale dell'Astigiano
Fossil whales and dolphins from the Pliocene, when the sea covered the Po Valley, are the stars of this museum in Palazzo del Michelerio, a former 16th-century monastery. Displays run through vaulted cellars to an aquarium recreating the ancient seabed; a visit takes an hour or two, with English audio guides and booklets.
