As an F1 fan, I had to visit here. The only surprise is that it took so long to do so.
Documented well enough on wiki that I don’t need to repeat it all here: https://en.wikipedia.org/wiki/Reims-Gueux
After yet more driving on this epic drive day, I stopped in the pit lane of the old Reims F1 circuit. To be fair, the location isn’t properly urbex, but still, it’s an abandoned structure so for me it still counts. The stands had been barricaded off and while it would have been easy to jump the fence, I was on a time schedule and had to limited myself to a pit lane walk. It’s amazing that the cars needed so little space to refuel and pit, and makes todays F1 seem overly complicated in comparison
