Known locally as “The Castle,” the Benjamin Bosworth House is a rare late-18th-century Federal landmark set on three private acres in Eastford, Connecticut. Listed on the National Register of Historic Places, the 4,538-square-foot residence retains the details antique-home devotees seek: 11 fireplaces, hand-carved mantels, doors and window details, original built-ins, stenciled floors, an antique kitchen basin, copper sink and wooden drainboard. Its defining architectural feature is the dramatic full-height monitor, believed to be among the earliest in Connecticut. According to the current owner’s research, its upper hall was first used as a Masonic lodge in the winter of 1800 and still contains built-in benches and fireplaces. Grand halls, a formal parlor, dining room with original China closet, sunlit keeping room, studio and workshop reflect a home designed for both purpose and presence. Recent preservation work includes traditional lime-and-sand plaster in the parlor and second-floor hall, plus chimney cleaning, inspection and new parging where needed. Four bedrooms, 2.5 baths and centuries of history await the next dedicated steward.
