Willie Stargell of the Pittsburgh Pirates hit the longest home run at Olympic Stadium on May 20, 1978, driving the ball into the second deck in right field for an estimated distance of 535 feet. The yellow seat that marked the location where the ball landed has been removed from the 300 level. The seat is now preserved at the Canadian Baseball Hall of Fame. Stargell also hit a notable home run at the Expos' original Montreal home, Jarry Park, which landed in a swimming pool beyond the right field fence.
