Memorial Stadium was a sports stadium in Baltimore, Maryland, that formerly stood on 33rd Street. It stood on an oversized block also bounded by Ellerslie Avenue (west), 36th Street (north), and Ednor Road (east). Two different stadiums were located here, a 1922 version known as Baltimore Stadium, Municipal Stadium, and Venable Stadium and the stadium that, when finally completed in 1950, would become known as Memorial Stadium, and for a time, Babe Ruth Stadium in reference to the then-recently departed Baltimore native. The stadium was also known as “The Old Gray Lady of 33rd Street”, and also (for Colts games at least) as “The World’s Largest Outdoor Insane Asylum.” {ref: Cooper Rollow, Chicago Tribune, 1959}.
