A building of almost Cistercian austerity, this five-bay Federal house belonged to Lemuel Clark Richmond, owner of a whaling fleet, and originally stood closer to the bay. When it came into the possession of the Herreshoff family in the 1860s, it was moved and expanded with several rear additions. Now a private museum, it is at the center of what can be viewed as an informal Herreshoff district, which includes the A. Sidney Herreshoff House at number 125 (built around 1940) with its attached model room, and the simple mansarded box at number 140, built as the Herreshoff Company's guest house. A stone marker, erected in 1963, marks the site of the Herreshoff works and records the firm's innovations in the technology of yachting and achievements in building America's Cup winners.
