New England town commons, such as this one in Greenfield, Massachusetts, were originally “common” areas, open for any resident to let their livestock graze. Commons were also used for public celebrations and militia practice. This view is from the west side of the common looking toward the intersection of Main and Federal Streets. The large building is the Mansion House, which had retail space on the first floor and rooms on the upper floors. Trolleys carry passengers up and down Main Street in this early 20th century view.
