The world is full of interesting museums telling us of stories that once were, are, and those that may come to be. We are lucky to have such spaces where we can learn about new destinations we visit or ones we are familiar with. Regardless of where you end up, visiting at least one museum is a must and it doesn’t have to be the most exquisite museum. In fact, unusual museums can sometimes be the most interesting ones, and if you’re the type of traveler who likes strange and unexpected, here are the top five most unusual museums in the world for you to explore right from home.

A museum that can only be seen underwater? It’s not a dream. In Cancun, Mexico, you can embark on a once-in-a-lifetime adventure below water and explore the Cancun Underwater Museum. Since 2010, scuba divers and snorkelers have been able to swim through this museum and see more than 500 figurines and objects spanning across the ocean floor (with more to be added). If you don’t want to snorkel or scuba dive, there’s an option to go on a guided tour via water boats with glass bottoms.

You can pretty much say there’s a museum for anything nowadays. One of these unusual museums is the Sulabh International Museum of Toilets located in Delhi, India. You can see the oldest toilets displayed dating back to 2500 BC all the way to the most high-tech ones available today. They range from standing and plush toilets to intricately designed ones and some that look completely uncomfortable to sit on. There are toilets once belonging to emperors and others that were owned by the common folk. Aside from toilets, the Museum also has a selection of unusual “toilet poems” written and read to help pass the time.

There are about 200,000 items to see, and some of these include human fetuses, deformed and mutated human body parts and those of animals.
