Together with its two neighbors to the south, this townhouse at 6 Walnut Street represents the development of the South Slope of Beacon Hill in the second half of the 19^th century, when larger estates continued to be carved up for housing, typically in the Italianate/Second Empire styles. Built in 1856, this residence was constructed on one of the last undeveloped lots in the area and was originally owned by George W. Simmons. Simmons was the owner of a well-known clothing emporium at Oak Hall, North Street, where he sold all kinds of ready-made clothing for men, including that needed by sailors, as well as sets of clothing for those headed for the California gold fields. His business was renowned also for its ambitious and creative advertising campaigns. Simmons died in late 1882, leaving this property to his heirs who sold the property. After successive ownership, the residence was converted to a boarding house during the Great Depression and rented out to families who could no longer afford the large single-family dwellings in the city. After WWII, in 1945, the boarding house was converted into the first Relocation Hostel for Japanese Americans in New England. The mission of the Relocation Hostels was to provide temporary lodging and career guidance to Japanese Americans who had been uprooted from their homes because of unfounded accusations of sabotage during World War II. Massachusetts joined New York, Pennsylvania, Illinois, and other states in establishing these hostels. Today, the residence is a four-unit condominium.
