The Guishan Han Dynasty Tombs are the most atmospheric of Xuzhou's several burial sites from the Western Han period (206 BC–9 AD). The complex consists of two parallel tunnel systems cut horizontally into a granite hillside — one chamber for the king of Chu, one for his consort — each running dozens of metres into the mountain and opening into a series of side chambers that once held food, wine, and grave goods.
The jade burial suits (one for the king, one for the queen) are the highlight. These remarkable objects — thousands of small jade squares sewn together with gold, silver, or bronze wire depending on the deceased's rank — were believed by Han people to preserve the body and ensure immortality. The craftsmanship is extraordinary, and the suits are displayed in a well-lit chamber where you can examine the construction closely. The tunnels are cool year-round, which is a comfort in summer. Allow ninety minutes.
