When it comes to free museums, most people think of Washington DC. You may be surprised to learn that Maryland has a handful of them as well, and they're one of a kind. Here are just 7 of them to start with. How many did you know about?

1. National Museum of Health and Medicine (Silver Spring)

This hidden gem started as an Army Medical Museum during the Civil War. Now, its collection has expanded to include medical oddities, disease, and more. All sorts of human bones and organs are on display, making for a fascinating (yet somewhat morbid) museum trip.

Address: 2500 Linden Ln, Silver Spring, MD 20910

2. The Baltimore Museum of Art (Baltimore)
