What is the name of the museum dedicated to Sherlock Holmes at 221B Baker Street?

The museum dedicated to Sherlock Holmes at 221B Baker Street is called The Sherlock Holmes Museum. It is a privately run London museum devoted to Arthur Conan Doyle's fictional detective and the world of the Holmes stories.

The museum opened in 1990 inside a Georgian townhouse that is presented as Holmes and Dr. Watson's Baker Street residence. Its rooms recreate the period associated with the stories, including Holmes's study, Watson's room, and Mrs. Hudson's quarters. Exhibits include Holmes memorabilia, period furnishings, wax figures, and objects inspired by different adaptations.

The address is famous but historically unusual. In the original stories, 221B Baker Street is fictional, and the street did not have numbers reaching 221 when Doyle began writing about Holmes. The museum was officially assigned the 221B designation in 1990, although its building lies between modern street numbers 237 and 241.

A common mix-up is confusing the museum with the British Museum or Madame Tussauds. The London Dungeon is also unrelated. The museum is specifically associated with Holmes, Watson, and their fictional Baker Street rooms.
