The Swiss village nearest to Reichenbach Falls in the Sherlock Holmes canon is Meiringen.
In Arthur Conan Doyle’s “The Final Problem,” Dr. Watson travels to Meiringen after receiving a message that Holmes has apparently been killed at the falls. The story places the climactic confrontation between Holmes and Professor Moriarty at the nearby waterfall in the Bernese Oberland.
The real Reichenbach Falls lie within the municipality of Schattenhalb, but Meiringen is the recognized nearby town associated with the Holmes episode. That distinction can cause confusion: the falls are not technically inside Meiringen itself, although the town is the practical gateway and the location most closely tied to the fictional event.
Meiringen later embraced its Holmes connection with a Sherlock Holmes museum, a monument, and memorial references near the falls. In the canon, the apparent deaths at Reichenbach mark the end of “The Final Problem”; Doyle eventually brought Holmes back in “The Empty House.”
