The Bikini Bottom Historical Museum is a Museum that appears in the two episodes and one video game: "Atlantis SquarePantis," "Are You Happy Now?" and SpongeBob's Atlantis SquarePantis. It resembles a Viking ship. It contains ancient artifacts, and other relics, such as the Atlantian Amulet, which SpongeBob and Patrick completed to get a trip to the underwater city of Atlantis. Mr. Krabs took admission there (unofficially). Squidward was seen painting pictures that relate to Atlantis. It includes many artifacts, art, historical items, and many other things of ancient history.
