The Vasa Museum is all about the ship named Vasa - the ship was a fantastical failure, the museum is doing quite well as far as I know. :)

(The museum spends a lot of time documenting "how could this have gone so wrong?")

The ship was a gigantic failure due to serious design flaws.

The project to build it was a gigantic failure and caused the Wasa's eventual demise.

The ship sank during its maiden voyage.

right in the harbor!
