Training Field School in the morning sunlight. The Charlestown Training Field (aka Winthrop Square) was established in the 1640s specifically for local colonial militia units to drill and train. The Training Field School, built in 1827, was initially located on the western edge of the Training Field and was moved in 1847. The school functioned until the early 1970s when it was converted to condominiums. For over almost four centuries, the Training Field has functioned as a cow pasture, a training field, an open gathering space, and a place of memorial. Artifacts and pottery discovered during an archaeological dig in 2013 determined that the area was occupied by the indigenous Mishawum people beginning 3-4000 years ago.
