Hidden along Marshall Street in Boston’s Blackstone Block, the historic Boston Stone is one of the city’s most overlooked colonial landmarks. Originally brought from England around 1700 by painter Thomas Child and used as a millstone for grinding paint pigments, it later became a familiar local reference point and was embedded into the wall of a building where it remains today. Over the years, legends claimed it marked the center of Boston and served as the starting point for measuring distances from the city, though historians debate those stories. Whether viewed as an industrial artifact, a colonial curiosity, or a piece of early Boston mythmaking, the Boston Stone offers a small but fascinating connection to the city’s earliest days.
