This is the Potter residence, also called the Iwanaga Bungalow, at Higashiyamate No. 12 (present day Nagasaki City Historical Museum of Private Schools at the Former Foreign Settlement). The building built by the Walsh Company served as the United States Consulate between 1861 and 1865. For a short while after 1865, it served as the Prussian consulate; after it was rebuilt in 1868, it served as the Russian Consulate. The building was used as a field hospital during the Satsuma Rebellion of 1877, after which it became the Potters’ residence from October 1878. An impressive stone wall circumscribes the residence.The building in the rear is Higashiyamate No. 6.
