Let's face it: The word for "tunnel" in German is just "Tunnel" - so there's nothing left to talk about, right? Not quite. When learning a new language it's just as important to know what words are the same (or almost the same) in both languages, so that our brains can establish a pattern and better predict what other words might be similar as well.

🧠 Fun little fact about the Mozart Tunnel in Würzburg (Bavaria):

🎶 The tunnel walls display a color-coded translation of Mozart’s "Eine kleine Nachtmusik"—each tile’s hue and position correspond to musical notes from the famous serenade. This unique visual score, created by artist Julia Breunig in May 2021 for the Mozartfest centenary, turns a dull underpass into a walk-through piece of musical art.
