Sanxingdui ("three star mounds") was a Bronze Age city ~40km from Chengdu, built around 1600 BC and lasting 500 years. Tens of thousands lived behind walls 40m thick at the base—likely flood defenses. Ritual pits yielded 100+ bronze heads, elephant tusks, and cowrie shells sourced from the Indian Ocean.
