Shanghai Navy YMCA, Heritage building in Huangpu District, Shanghai, China

Shanghai Navy YMCA is a six-story reinforced-concrete building at 630 Sichuan Middle Road, facing west on an L-shaped plot formed from two lots at the corner with Hong Kong Road. Designed by American architect Arthur Quintin Adamson of the YMCA Building Bureau, it is a strict Modernist structure with a point-type plan, pile foundations and ribbed hollow floor slabs. Its entrance on Sichuan Road leads only to the lifts, while the rest of the ground-floor street frontage was let as shops.

The YMCA's wartime fund surplus of $300,000 financed the building, designed by architect Arthur Quintin Adamson. Its cornerstone was laid on 8 May 1922 with a time capsule, and it opened on 10 October 1923. In March 1927 women refugees sheltered in its gymnasium. Japan occupied it in 1941; after 1949 it became the YMCA's second branch, and in 1959 the Shanghai housing authority took over.

The building's name comes from its Chinese abbreviation, Haiqing, short for the Navy YMCA. Its third-floor restaurant served both sailors and Shanghai residents, with lunches popular among local businessmen, and an oak wall panel hung with photographs of sailors and scenery. The soda fountain sold takeaway drinks for 50 people at a time.

The building stands at 630 Sichuan Middle Road, on an L-shaped plot with 24.7 m of frontage on Sichuan Road and 57.9 m on Hong Kong Road. The main entrance on Sichuan Road leads only to the lift through a small vestibule, separate from the ground-floor shops. The former swimming pool, tiled in green and white mosaic, measures 18.3 m by 6.1 m.

The 1922 foundation stone held a time capsule with a Bible, a sailor's will, US Navy regulations, a Mother's Day letterhead, Shanghai newspapers and coins. The architect was Arthur Quintin Adamson of the YMCA Building Bureau, not a Chinese designer.
