Boston Common, the oldest public park in the United States, has a rich history of serving various purposes over the years. From pastureland and burial ground to military training field and site for public executions, it has seen it all. Eventually, it evolved into a recreational green space, with tree-lined paths, a manmade pond, and a fountain fed by an aqueduct. Today, Boston Common stands as a picturesque and popular spot for leisure and relaxation in the heart of the city.
