Tucked into Macbride Hall on the Pentacrest, this is one of the oldest university museums in the country and still has the wood-and-glass feel of a Victorian cabinet of curiosities. The Hageboeck Hall of Birds — three thousand mounted specimens arranged ecologically — and the Iowa Hall diorama gallery are the two not-to-miss rooms.
Admission is free. Kids tend to love it; adults find the late-19th-century display cases almost as interesting as what's inside them.
