Two Parallel Tunnels Through a Han Prince’s Hill: Guishan Tomb at Xuzhou
双甬穿山尽两千年，楚王长卧龟山巅 Shuāng yǒng chuān shān jìn liǎngqiān nián, Chǔwáng cháng wò Guīshān – Two tunnels pierce the hill for two thousand years; the Prince of Chu sleeps long inside Turtle Mountain
正文：龟山汉墓 Guīshān Hànmù the Guishan Han Tomb is the hollowed-out burial of Liu Zhu, Prince of Chu in the Western Han, cut clean into the solid granite of Turtle Hill around 2,100 years ago – and cut with a precision that still unsettles engineers. Two parallel corridors, each nearly sixty metres long, run into the rock with a tolerance so fine that modern laser checks found them accurate to a fraction of a degree; the walls inside are dressed flat without mortar, and the chamber rooms spread over hundreds of square metres like a palace turned upside down underground.
The corridors are the fame of the place. Stand at the mouth and the two tunnels run shoulder to shoulder into the dark, their far ends a pinpoint of light – each carved from the outside in, meeting in the middle with walls so straight that a coin’s edge would catch along them. An “iron curtain wall” of stacked stone once sealed the outer corridor; thieves found the gap anyway, centuries ago.
Inside, the tomb reads as a palace in stone. The bedrooms, kitchen, stable and banquet halls of the afterlife each hold their carved details – water channels for sacrifices, niches for the coffins, and the pits where chariots were buried for the prince’s journey. Exhibits around the site display the horse-drawn funeral vehicles found here, lacquered red against the grey rock.
Allow an hour and a half: the corridors, the chamber circuit and the small exhibition hall, then the hilltop park above where stone markers explain the dig. Guides make the precision story land better than plaques alone – and the cold of the tunnels in summer is its own reward in July.
Practicalities
Beyond the tomb, the same 徐州市 Xúzhōu Shì Xuzhou City keeps more places worth the detour: 云龙湖 Yúnlóng Hú Yunlong Lake for the water views, 狮子山楚王陵 Shīzǐshān Chǔwánglíng the Lion Hill mausoleum for the terracotta army, 云龙山 Yúnlóng Shān Yunlong Mountain for the pavilion walks, or 户部山 Hùbù Shān Hubushan for the merchant courtyards – four more doors into the same 徐州市 Xúzhōu Shì Xuzhou City. Once the tunnels are walked, our Xuzhou food map fills the day.

Words and Names
flowcloud would say the Guishan tomb is engineering wearing a crown: two corridors straighter than modern drills, a palace flipped underground, and a prince who took his whole household’s address with him. All checked November 2026.
Getting there: Guishan Tomb sits on Turtle Hill in northwest Xuzhou, about twenty minutes from downtown by bus or taxi; admission covers the tomb and exhibition hall, the corridors stay cool year-round, and weekday mornings are the quiet slot. All checked November 2026.
