Beacon Hill is one of the most charming and unique neighborhoods. It encompasses an area which is bordered on the North by Beacon Street running up the hill at the perimeter of the Boston common to the State house, which was designed by Charles Bullfinch in 1797, and is one of the finest examples of his work. It runs down the foot or the "flat" of the hill to the banks of the Charles river, where in the summer one can hear the music of the Boston Symphony Orchestra wafting up from the Hatch Memorial shell on the banks of the Charles. The bottom of the west slope of the hill is bordered by Cambridge Street.
