The site was discovered in 1929 by a farmer digging an irrigation ditch and excavated seriously from the 1980s onward. It belonged to the Shu kingdom, a contemporary of the Shang dynasty in the second millennium BCE, and its material culture shares almost nothing with the bronze tradition of the Yellow River valley. Two sacrificial pits yielded hundreds of objects, and a further set of pits discovered in 2020 added significantly to the collection.
The objects
The signature pieces are enormous bronze masks with protruding eyes and exaggerated ears, some over a meter wide; a bronze standing figure over 2.6 meters tall in a long robe; and a bronze sacred tree almost four meters high with branches, fruit and birds. There are also gold masks and gold foil ornaments, jade weapons and large quantities of elephant tusks. The eyes are the recurring motif, and the scale is consistently larger than visitors expect.
Why it matters
Sanxingdui forced a revision of the standard account of early Chinese civilization as a single Yellow River origin. Here was a sophisticated bronze-working state with its own iconography, in a region previously assumed to be peripheral. The eyes, the trees and the strange composite animals have no clear parallel elsewhere, and their meaning remains debated.
Practical notes
The museum is in Guanghan, roughly an hour by road from Chengdu, and is best done as a half-day trip or combined with Jinsha on the way back into the city. Allow two to three hours; the site is large and the main exhibition hall is popular, so go early. Read up briefly before you arrive, because the displays are visually overwhelming and the labels alone do not explain the puzzles.
