Aachen was the first German city I spent any time in (an overnight stop on my way to Paris). It’s where I learned about the 8-minute beer and that in most cities outside of major metro areas the general population does not speak English.

Being a Nazi stronghold there are many reminders of WWII - one interesting place is called the Musik Bunker, a converted Nazi command center. With it’s 2 meter thick steel reinforced concrete walls keeping the sound in and neighbors happy it has a bar, 60 rehearsal rooms and a 350 seat concert hall. Travel outside of the city and the remnants of the Siegfried Line are visible everywhere... from Dragon’s teeth used to stop tanks to smaller bunkers.
