There’s hardly anything left of the track, only this little monument with the names of the F1 winners and the winners of the motorcycle endurance races that were run upto the 80s.
If any of you F1 fans ever go to Barcelona I’d highly recommend renting a bike and taking a lap around. There’s an uphill section that can be a bit tough, but the downhill cambered turns are amazing. The circuit runs near Plaza España and the famous Montjuïc Fountains, as well as the 1992 Olympic Stadium and the Greek Theater. It’s overall a cool lap.
Here’s the other bit of the plaque: https://imgur.com/a/m01eMMB
