Yes, allegedly the longest straight road in .. eh ..Munster or somewhere. Renowned for speed record attempts. I remember a caravan-towing speed record there when I was a child. I kid you not. AFAIK the record still stands.
But maybe more interestingly, it was also part of the course - on public roads - for grand prixs back in the '30s . Some spiffing videos here:
