Lord. It is still used as a residence.","why_significant":"The nomination argues the house is Waltham's most highly eclectic late 19th-century mansion, with a castellated corner tower and Flemish gables unique in the city. It is a rare Boston-area example of a castle-like mansion. It is also associated with Rufus E. Lord, a prolific Waltham builder of the late 19th and early 20th centuries.","narrative":"Known as Lord's Castle, this mansion at 211 Hammond Street in Waltham was completed in 1886 by local builder Rufus E. Lord. It sits on a prominent corner lot on the slopes of Prospect Hill, chosen for its commanding views. Built of yellow brick with fieldstone porch posts, it has an irregular plan dominated by a robust three-story corner tower with corbelling and castellation. Other details include Flemish gables, a Palladian window over the entrance, stained glass beside the double front doors, and a copper-edged hip roof. Inside are eight mantels, each of a different design, a fireback bearing a coronet, and mottled hearth tiles. Lord was among the builders who shaped Waltham's private houses and public buildings, and his Armory at Sharon and Cushing Streets is also well known. The house is regarded as architecturally unique in the city and a rare castle-like mansion in the Boston area. It remains a residence in good condition with no major alterations.","period_of_significance":null,"architect_builder":"Rufus E.
