The expansive Jinsha Site Museum (金沙遗址博物馆, Jīnshā Yízhǐ Bówùguǎn) has a collection of 6000 objects from the 3000-year-old Shu kingdom. The relics, created between 1200 and 650 BCE, were uncovered in 2001 on a riverbank in the city's western suburbs. The museum comprises the large sacrificial zone of the dig site and an exhibition hall. The first will give you a feel for the layout, though it's empty except for a few elephant tusks. The relics, displayed elsewhere, include functional and decorative items, from pottery and tools to jade artifacts, stone carvings and gold masks. All labels and signage are bilingual.
Use exit C of the Jinsha Site Museum station on metro line 7; the ticket office is about 400m north.
An audio guide (in English) is also available with a deposit.
