In 1955, the Spanish Grand Prix at Pedralbes was scheduled to take place, but a terrible accident at the 24 Hours of Le Mans that killed more than 80 people resulted in regulations governing spectator safety, and the scheduled Spanish Grand Prix (like many others) was cancelled that year and for the subsequent 2 years (also owing to more problems with money to hold the race), and the pedestrian-lined street track at Pedralbes was then never used again for motor racing.
