Oh no. We lived in Bielefeld in 1990 for 6 months before it “didn’t exist”. I was surprised to find out there was a town of >300,000 people in Germany I’d never heard of and we were moving there.
Shhhh their secret is safe with me. Hardly any outside tour groups know about it to this day. If you find yourself visiting Bielefeld though and want to explore some interesting places in and around the city there is a castle, zoo, forest trails, beautiful old town, Dr Oetker train station and spice factory and art museum. It’s historical fame and wealth were in linen weaving and some factories still exist, we have friends who were part of this legacy.
My absolute favorite nearby towns were Detmold and Lemgo.
Thanks for the pleasant memories, or maybe it was a dream...
