The Reichenbach Falls in Meiringen, Switzerland, has a total drop of 250 metres. At 90 metres, the Upper Reichenbach Falls is one of the highest cataracts in the Alps. This is the place where Sherlock Holmes apparently died at the end of Sir Arthur Conan Doyle’s Sherlock Holmes series "The Adventure of the Final Problem".
Accordingly, to the storyline of "The Adventure of the Final Problem", Watson was tricked by Holmes's greatest opponent, the criminal mastermind Professor Moriarty, to return back to the hotel where he was then staying with Holmes. After Watson realised at last what had happened, Watson rushed back to Reichenbach Falls only to find no-one there, although he did see two sets of footprints going out onto the muddy dead-end path, but none coming back. Towards the end of the path, there were also signs that a violent struggle had taken place. Apparently, it seemed that Holmes and Moriarty have both died, falling to their deaths down the gorge whilst locked in mortal combat.
