Mutter Museum

You may want to think twice about bringing your kids to the small yet fascinating Mütter Museum. Housed within the College of Physicians, Mütter is dedicated to the exposition of medical oddities. While most museums like this fill their halls with old pictures and antique scalpels, this rather cramped 19th-century building overflows with jars containing about 20,000 preserved body parts and other objects. Some highlights include items that belonged to Marie Curie, a tumor removed from Glover Cleveland's mouth, an informative display on Siamese twins and the tallest skeleton on display in the U.S.

While this museum is fascinating, be prepared to feel grossed out. According to one TripAdvisor user, "I will caution that it is not for the squeamish as some of the exhibits might be disturbing. But that is also what made this museum so unique! For us it was a 'must see' in Philly."

The Mütter Museum is located a few blocks northwest of Rittenhouse Square just south of Fairmount Park. It is open every day of the week from 10 a.m. to 5 p.m., and admission is $15 for adults and $10 for children. For more information, visit the official website.
