Baden is German part of Switzerland and has a population (as of December 2020) of 19,621.
How about a lovely walk through a 39-meters covered wooden bridge that connects two banks of the river Limmat? The bridge was built as early as the 13th century and was constantly destroyed by acts of nature and war. Today’s bridge was built in 1809 and it has served as the main traffic axis ever since. Designed by the famous architect, Blasius Balteschwiler, this wooden bridge is such an architectural gem.
