The tomb of Zhao Mo, the second king of the Nanyue Kingdom, was discovered in 1983 during construction work on Xianggang Hill, near the northern edge of Yuexiu Park. Dating to around 122 BC, it is the best-preserved Han-dynasty royal tomb found in southern China.
The museum is built directly over the excavation site, so you descend into the actual tomb chambers. The centrepiece is Zhao Mo's jade burial suit, stitched together with silk thread — one of only a handful ever found. The collection also includes bronze mirrors, gold seals, and a remarkable set of iron swords. A separate gallery covers the history of the Nanyue Kingdom, which controlled much of what is now Guangdong and northern Vietnam.
The museum sits just north of Yuexiu Park's main entrance on Jiefang Bei Lu. Allow about an hour for a thorough visit.
