Not many museums have to start with a caveat explaining why they receive complaints from visitors, but, if you house the “largest collection of human material in the United States,” you’re bound to get a few raised eyebrows. In addition to medical exhibits showing various stages of fetal development (and abnormal development), the museum features examples of medical curiosities. If you’ve ever wondered what a scrotum with Elephantiasis looks like, now’s your chance! The museum is open 10:00 am to 5:30 pm and is accessible from the Red Line (Silver Spring and Forest Glen stations).
