The Mushroom City Natural History Museum is a natural history museum located in a square somewhere in the Central District of Mushroom City, the capital of the Mushroom Kingdom. As the name implies, it is a natural history museum, evidenced by a banner showing a dinosaur exhibition inside. Even though it is a museum, it does contain some objects from the Mushroom Kingdom's modern history.
The museum makes its first appearance in The Mario Channel: MARIOBUSTERS, where Fishy Boopkins tried to steal the Mushroom Kingdom Declaration of Independence, before he was apprehended by the police.
The museum reappears in If Mario was in... Assassin's Creed Origins, where Mario finds a golden orb that sends him back in time.

So far, there are only four known artifacts that are kept in the museum.
