Original Jarry Park Stadium before the Expos
Before we get into how Parc Jarry came to be chosen as the home base of the
Montreal Expos (we will look at the crazy other ballparks that were under consideration in just a bit) or even how the Expos came to be the newest Major League franchise in 1969... lets explain one misnomer which is very common... that Jarry Park Stadium was a converted Double-A ballpark. We've seen that in print in several locations. Jarry Park Stadium was never used for professional baseball in any capacity before the Montreal Expos. As you can see above the "original Jarry Park Stadium" was just a small 3,000 seat amateur ballpark and it had never been used for any type of professional baseball. There have only been 2 stadiums ever used for professional baseball up until this point... Atwater Park from 1890-1927 and Delorimier Downs from 1928-1960. (The Shamrock Club located right across the street from Jarry Park was also used for some Sunday games in the early days) and those 2 (or 3 with the Shamrock) are the entirety of Montreal's professional baseball stadium history up until 1969.
