It was located on the northeast corner of Columbus Avenue and Walpole Street (now Saint Cyprian's Place), just southwest of Carter Playground.

The ballpark was across the New York, New Haven and Hartford Railroad tracks, to the south, from the eventual site of the Huntington Avenue Grounds, home field of Boston's American League team prior to the building of Fenway Park.

This team eventually adopted the official nickname "Braves," just a few years before abandoning South End Grounds.

The Red Stockings dominated the National Association, finishing just two games behind the leaders in 1871, then winning four straight pennants to close out the NA.

Berlin Street disappeared, and Columbus Avenue was constructed, running just outside the right field area, replacing wooden buildings that had once stood there.

On September 12, 1911, 44-year-old legend Cy Young pitched the final home game of his career in a Boston uniform at the grounds against the New York Giants and fellow future Baseball Hall of Famer Christy Mathewson.

The former site of the grandstand and the infield is located where Northeastern University's Interdisciplinary Science and Engineering Complex (ISEC) currently stands, between the Columbus Parking Garage and Ruggles Station of the Orange Line of the Massachusetts Bay Transportation Authority.
