The square is adjacent to the finish line of the Boston Marathon and a monument in the park commemorates the marathon.
The name Copley Square is frequently applied to the larger area extending approximately two blocks east and west along Boylston Street, Huntington Avenue, and St. James Avenue.
The square is bounded by Boylston Street on the north, Clarendon Street on the east, St. James Street on the south, and Dartmouth Street on the west.
From late April until mid-November a farmers' market is open in Copley Square every Tuesday and Friday. Organized by the city of Boston, it is located along the south and west edges of the square.
