Shi'erqiao Site, Archaeological site in Qingyang District, Chengdu, China.

Shi'erqiao is an archaeological site on the south side of Shi'erqiao Road in Qingyang District, Chengdu, within the compound of the Chengdu Institute of Cultural Relics and Archaeology. Excavated in 1985–1989, it covers about 19,000 square metres and yielded well-preserved wooden building components and small stilt-style wooden structures from the Shang and Zhou periods. The excavated area was backfilled with soil in 1989.

The site was discovered in late 1985 when construction crews digging a foundation pit on the south side of Shi'erqiao Road uncovered pottery fragments and round wooden components. Excavations in two phases between 1986 and 1989 covered 1,500 square metres of an area estimated at 19,000 square metres. It was listed as a Sichuan provincial cultural relic protection unit on 16 January 1987 and as a Major Historical and Cultural Site Protected at the National Level on 25 June 2001.

The pottery and tools found here reveal how people organized their homes and performed daily tasks across many centuries. These objects show the practical skills and craftsmanship that shaped the communities living in this area.

The excavated area was backfilled with soil in 1989, so there are no open trenches to visit. The site lies on the south side of Shi'erqiao Road, on the grounds of the Chengdu Institute of Cultural Relics and Archaeology, and is not open to the public.

The excavations here have revealed how ancient settlements in the region developed and changed over very long periods. These findings provide important clues about the early patterns of city formation in ancient China.
