Mütter Museum

There’s truly no other place in the world like this unique and disturbing museum. It’s probably best that photography is strictly prohibited inside, because that might spoil the bizarre surprises that wait for those who haven’t been yet. The Mütter is a medical museum in Center City that’s part of the College of Physicians of Philadelphia. Be forewarned: Its world-renowned collections are often somewhat disquieting—biological oddities, anatomical and pathological specimens, wax models, and antique medical equipment. (Wooden cabinets in one gallery hold drawers full of objects that people have swallowed!) The gift shop may be the most interesting museum store you’ll ever visit, and might be the only place that sells conjoined-twin cookie cutters.
