Tour the Museums 150,000 square feet of exhibit space to visit Africa, Asia, Europe, the Arctic, South and Middle America, the Pacific Islands and a Costa Rican rainforest or take a small step back in time to the turn-of-the-century Streets of Old Milwaukee and to ancient Mediterranean civilizations. Or, take a giant leap back more than 65 million years to The Third Planet, see the worlds largest-known dinosaur skull and a life-sized replica of Tyrannosaurus rex.
