A paragon of timeless beauty with a rich heritage, this admired landmark residence built in 1837 presides atop picturesque Mount Vernon Street on the crest of Beacon Hill, benefitting from the southerly sunlight and large, lush garden that graces its grand Greek Revival frontispiece. Designed by architect Edward Shaw for prominent merchant Adam W. Thaxter, Jr., this rare jewel has been carefully restored and enhanced as a comfortably refined home of extraordinary character, notable for its splendid details and graceful ensemble of living/entertaining rooms. Striking Ionic pilasters adorn the bow-front sitting room. Other highlights include 14 fireplaces, double parlors, a dramatic curvilinear staircase, and top-floor octagonal observatory room commanding 360-degree city vistas. Opening to a captivating garden terrace, the dine-in gourmet kitchen is bright and airy below a peaked skylight. Served by an elevator, the home offers a versatile layout with the bedrooms on various levels.
