It is also tied to Harrison Loring, an early South Boston builder of iron steamships, and it contributes to the character of the Independence Square neighborhood. The detached brick Victorian mansion is rare in Boston's dense neighborhoods, and South Boston has the city's most notable concentration of them.","narrative":"Built in 1865 on East Broadway in South Boston, this three-story brick mansion faces Independence Square and was the home of Harrison Loring, who ran one of the first South Boston shipyards building iron steamships and their engines. The house shows the French Second Empire style through its bell-cast mansard roof, central projecting pavilion, brownstone-framed windows, classical moldings and symmetrical arrangement of bays. A matching two-story carriage house with a cupola was built the same year. The architect is unknown, but the interior may reflect naval construction methods, including dovetail joinery, wall air circulation and cabinets with counterswinging doors, suggesting shipyard carpenters built it. Detached brick Victorian mansions are uncommon in Boston, and South Boston holds the city's most notable group of them. The house was designated a Boston Landmark in 1981. It later served as a convent and chapel under the Catholic Church, then returned to private residential use. It is the only surviving property tied to Loring.","period_of_significance":"1800-1899","architect_builder":"Unknown; believed to have been built by skilled shipyard carpenters","architectural_style":"French Second Empire","criteria":["B","C"],"status_note":"Occupied as a private residence; condition listed as excellent and altered.
