This museum definitely tops the list of unusual attractions in the bustling city. Part of the Siriraj Hospital in Bangkok, the museum is known to be gruesome, freaky and just plain, and something you'll definitely be interested in – especially if you're not usually a fan of museums. The museum holds a collection of mummified cadavers of rapists and murderers, especially the country's most notorious serial killer who ate the livers of around 30 children, and that's not even the eeriest part! A part of the museum is especially dedicated to a collection of dead babies – preserved in various stages of their lives, most of which have deformities. You will be able to find various skulls and human bones along with preserved heads of humans. Visiting the Forensic Museum is a definite must especially if you like that sort of thing, however, if you have a weak stomach, maybe skip this museum and visit a history museum instead.
