中国银行南京分行旧址, Historical bank building in Xiaguan District, China

The former Bank of China Nanjing branch at 66 Dama Road is a three-storey reinforced-concrete building completed in 1923, one of Nanjing's earliest Western classical structures. Its main entrance has a porch carried by six two-storey-high Ionic columns. It stands just west of the former Jiangsu Postal Administration building.

The building was established in the early 20th century and played a central role in Nanjing's financial development during China's economic transformation. It marks a period when Western banking practices took root in the country.

The building's name still ties it to the Xiaguan office of the Bank of China Nanjing Branch, and after 1949 the site passed to the Yangtze River Water Resources Commission. Today it houses the Hydrology and Water Resources Survey Bureau of the Lower Reaches of the Yangtze River, so the former banking hall serves water-survey work rather than finance.

The building is easy to reach by public transportation, with several bus stops and metro stations within walking distance in the Xiaguan area. This location makes it simple to visit alongside other historical sites in the neighborhood.

The six Ionic columns of the entrance porch rise through two storeys, a detail easy to miss from the street. Since 1949 the building has belonged to the Yangtze River Water Resources Commission and now houses the Hydrology and Water Resources Survey Bureau of the Lower Reaches of the Yangtze River, so it is a working office rather than a museum.
