Congress Street Grounds, Sports venue in Boston, Massachusetts, United States

Congress Street Grounds is a sports venue in Boston, Massachusetts, United States. It consists of an open field with a marked diamond and simple spectator areas, used for local baseball games and community events.

The site opened in the late 19th century as a baseball ground and hosted professional games during that era. Over time, it was adapted for community use and remains a local sports spot.

On weekends, the field fills with local teams and spectators who gather along the edges to chat and cheer. The atmosphere is informal, with people bringing folding chairs and sharing snacks while the games unfold.

The grounds are easiest to reach on foot from nearby streets, and the flat layout makes them accessible for most visitors. Mornings and late afternoons are the best times to watch casual games, when the field is most active.

The grounds once had a grandstand that could hold thousands of spectators, a feature often overlooked today. Its outfield boundaries were unusually short, which led to many home runs during early games.
