Tomb of Marquis Yi of Zeng, Royal tomb in Leigudun Community, China

The Tomb of Marquis Yi of Zeng is a rock-cut pit 21 m long and 16.5 m wide, over 13 m deep, in Leigudun, Suizhou. Inside, a wooden chamber of 171 zimu timbers is divided into four rooms; the central room held the 65-bell set, the eastern room the nested lacquer coffins of the marquis and eight women, the western room 13 coffins, and the northern room weapons and bamboo slips.

The tomb was built for Marquis Yi of Zeng and sealed around 433 BC, at the end of the Spring and Autumn period or the start of the Warring States period. It was accidentally found in 1977 by the People's Liberation Army during factory construction at Leigudun. Excavation in 1978 revealed 15,404 objects, including a 65-bell bronze chime and the earliest known bamboo-slip funerary inventory.

The name follows an old custom of naming regional rulers by their fief and title. Visitors encounter the remains of a burial where objects were arranged by purpose and rank.

The eastern chamber served as the main burial space, while the other areas were divided by the type of offerings. Visitors today see a site made accessible through excavation and conservation work.

Inside was a set of 64 bronze bells spanning five octaves, one of the earliest complete finds of its kind. The bells show a developed tonal system and metalworking skills from that era.
