The Nasengässchen (Nose Alley) links Leichhof (the site of the original church cemetery, Leiche meaning corpse) and Grebenstrasse (possibly originating from Graben, a ditch) in the Altstadt.
There are heaps of theories as to its name, some referring to Zur Langen Nase (House of the Long Nose), a property in the Grebenstrasse first documented in 1568.
The most promising theory of all, however, is based on the abrupt 90° change of direction, given that a bend was in earlier times frequently called a “Nase“.
So that’s another 5 minutes of your life wasted on trivia….
I see German words like this, and I’m always struck by how long they are- one could make a sandwich in the time it takes a speaker to finish three sentences.
