An official Path Through History Site! The Chelsea Mansion is the former home of Alexandra and Benjamin Moore, located on the five hundred and fifty acre Muttontown Preserve. Inspired by a yearlong international honeymoon, this 40 room mansion was built in 1924 and is an outstanding example of the design ideas prevalent during the latter part of Long Island's Gold Coast era.
