KNOW YOUR HISTORY Originally built in 1976 for the Montreal Summer Olympics, the Big-O was the entrance for athletes to access the stadium where Athletics competitions were being held. At first, the O was also covered in rubber, but not long after the Olympics, skaters saw the potential and ripped all the rubber from the structure, revealing smooth concrete underneath. The popularity of the spot didn’t only come from the fact that it was a perfectly smooth, natural concrete mini-ramp, but it was also one of the only places in the city where you could find real concrete transitions to skate on.
