Winthrop Square / the Training Field is a city park in Charlestown with an 1872 monument honoring the men of Charlestown who fought in the American Civil War in 1861. This square is of national significance because of its connection to the Battle of Bunker Hill. On June 17, 1775, fighting between American patriots and British soldiers took place on or near what is now Winthrop Square. Since its creation in the 1640s, the park has served the citizens of Charlestown as farmland and pasture; it has been a military training ground, a schoolyard, a site for political rallies, a children's playground, and a peaceful retreat in a dense urban environment. Over time, Winthrop Square has undergone extensive changes, from an open field to an urban city park. Its current appearance is characterized by redesigns in 1872 and 1919. https://cps-ris.org/wp-content/uploads/2020/03/Winthrop-Square.pdf
