Originally built in 1893, this 25-foot townhouse was acquired roughly two decades later by R. Horace Gallatin, whose great-grandfather was a former Secretary of the Treasury. The 12,000-square-foot, newly renovated mansion includes a family room, living room, formal dining room and paneled library. There are also six bedrooms, eight baths, three powder rooms and three staff rooms. Several years ago, the mansion belonged to Habsburg Feldman, a Geneva-based auction house, before returning to residential use in the early 1990’s. Building Dimensions: 29 ft x 99ft
