Though it's officially called The College of Physicians of Philadelphia Mutter Museum, it's best known by its nicknames, the Mutter Museum or just the Museum of Medical Oddities. Whatever you choose to call it, this is not an attraction for the faint-of-stomach. Unborn fetuses in jars, petrified body parts, conjoined twins and, as part of an exhibition, Albert Einstein's brain, are just a few of the artifacts that chronicle the fascinating and sometimes gruesome story of medicine through the ages. Visit this incredible museum for an experience like no other, for a break from the humdrum, or for an appreciation of the medical profession and all that goes in to it.
