Unique and disturbing, there’s no other place like it in the world. It’s probably best that photography is strictly prohibited inside the museum, because it would be best not to spoil the bizarre surprises that await you inside. The Mütter Museum is a medical museum in Center City maintained by the College of Physicians of Philadelphia. Its world-renowned collections are (be warned) quite disturbing—medical oddities, anatomical and pathological specimens, wax models, and antique medical equipment. One section contains wooden cabinets with drawers containing objects that people have swallowed. No, that is not a misprint! The gift shop may be the most interesting museum shop you’ll ever visit, and could be the only place that sells conjoined twin cookie cutters!
