The archaeological discoveries of Sanxingdui resemble something out of a surreal horror movie: Gigantic, boxy heads. Creatures with stalk eyes. Hybrid beings with snake bodies and bird legs. On top of that, a four-meter-tall bronze tree, with mysterious birds perched on its branches. These dramatically illuminated artifacts can be admired at the Sanxingdui Museum in the northeastern part of the excavation site, about 40 kilometers from Sichuan’s capital, Chengdu.
