Madison Avenue Grounds aka Monumental Park was built by the Waverly Club as the first enclosed ballpark in baseball located in Baltimore, with spectator seating and player clubhouses, and was the site of the first intercity game played in Baltimore (Brooklyn Excelsiors 51, Baltimore Excelsiors 6) on September 22, 1860; it was the site of a 47-7 defeat of the local Marylands by the undefeated Cincinnati Red Stockings in 1869, and it was used by the Washington Olympics of the National Association for a professional game in 1871.
The ballpark was also part home to the Maryland club of the National Association, who had a brief fling as a professional club in 1873.
It closed by 1884.
