Questions and answers
What does Werdinsel mean?
Werd comes from old words for an island or river island and fell out of common use in the 16th century. Insel was added after the meaning was forgotten, so Werdinsel means “island island.”
Is Au-Höngg Zürich’s only Limmat river bath?
No. Flussbad Au-Höngg is one of four public river baths on the Limmat within Zürich.
