Former Post Office of Lingyuanxincun, Cultural heritage site in Nanjing, China.

The Former Post Office of Lingyuanxincun, also called Bajiaoting (Octagonal Pavilion), stands at the west end of Miaopu Road in Xuanwu District, Nanjing. Built in 1934, it is a two-storey building in a faux-antique style, with blue glazed-tile dougong brackets under the eaves, painted queti and beam frames, and a square double-eaved pyramidal roof covered in green glazed tiles. The main entrance is on the south side.

Built in 1934 as the dedicated post office for Lingyuanxincun, a villa district for senior Nationalist government officials. It was destroyed by fire in the winter of 1937 during the Japanese attack on Nanjing and rebuilt in 1947. From 1976 it served as housing for Nanjing postal workers before being left vacant; in June 2006 it was listed as a provincial cultural relic.

Locals call the building Bajiaoting, the Octagon Pavilion, after its square double-eaved pyramidal roof. It served the villa quarter of Lingyuanxincun, home to senior Nationalist government officials, and its south gate once carried a plaque inscribed by Lin Sen reading "Lingyuan Post Office". Since 2006 it has been listed as a Jiangsu provincial cultural relic.

The building sits in an easily accessible residential area and can be reached conveniently by public transportation. It is worth checking ahead of time whether the site is open for visits and if viewing is allowed.

The building is also known as the Octagonal Pavilion (Bajiaoting), a name that points to its square double-eaved pyramidal roof rather than to an octagonal plan. Its south gate once carried a plaque inscribed "Lingyuan Post Office" by Lin Sen, chairman of the Nationalist government.
