Hidden in the hills of Nanjing, China, are three enormous pieces of limestone that were meant to become one of the largest stone monuments ever attempted. They are known collectively as the Yangshan Quarry Stele, a colossal project ordered in 1405 by the Yongle Emperor of the Ming dynasty. The plan was to create a monumental stele in honour of his father, the Hongwu Emperor, at the Ming Xiaoling Mausoleum.

What Is the Yangshan Quarry Stele?
The Yangshan Quarry Stele is not a finished monument. Instead, it consists of three huge limestone components carved directly from the mountain: the stele base, the stele body, and the stele head. Yangshan had already served as a quarry for centuries, but the Ming dynasty transformed part of the site into an enormous imperial stone-cutting project. The intention was to produce a magnificent memorial for the Ming founder, Zhu Yuanzhang, whose tomb complex, Ming Xiaoling, lies in Nanjing.
The quarry therefore preserves something unusual: not merely an ancient monument, but the remains of a monument that never got assembled. The Yangshan site now forms part of the Yangshan Quarry Scenic Area, and local authorities recognise it as an important Ming cultural heritage site. The Jiangning District government describes the site as a provincial-level key cultural relic and notes its recognition for having the world's largest stele material.
The Yongle Emperor’s Ambitious Monument
The project began in 1405, during the reign of the Yongle Emperor, Zhu Di. He wanted a huge memorial stele that would celebrate the achievements of his father, Zhu Yuanzhang. The idea was based on a common Chinese practice of memorialising rulers and their achievements through monumental stone inscriptions. But the scale chosen at Yangshan was extraordinary.
Instead of quarrying a manageable block and transporting it to the tomb, workers carved enormous sections from the mountain itself. The three pieces were shaped separately so they could theoretically be moved, finished, and assembled at Ming Xiaoling. The result was far beyond the scale of an ordinary stele.

A Monument Planned to Be 73 Meters Tall
The proposed Yangshan monument was enormous even by modern standards.
The three surviving components are generally described as follows:
- Stele base: about 30.35 metres long, 13 metres thick and 16 metres high.
- Stele body: about 49.4 metres long, 10.7 metres wide and 4.4 metres thick.
- Stele head: about 10.7 metres high, 20.3 metres wide and 8.4 metres thick.
The long body stone was intended to be raised vertically onto the base. With the head placed above it, the completed monument would have reached a height of approximately 73 metres (240 feet). That projected height is what makes the Yangshan Quarry Stele so remarkable. The stones lying horizontally in the quarry today do not immediately resemble a 73-metre monument. Only when their intended arrangement is understood does the original scale become apparent.
More Than 31,000 Tonnes of Stone
The weight is even more astonishing. Commonly cited estimates put the three unfinished components at approximately:
- Base: 16,250 metric tonnes
- Body: 8,799 metric tonnes
- Head: 6,118 metric tonnes
Together, these figures total roughly 31,167 metric tonnes.
In other words, the proposed monument represented more than 31,000 tonnes of stone before it was even transported or fully finished. There are slightly different figures in modern descriptions of the site. The Jiangning District government, for example, provides a total weight of about 26,000 tonnes and a total height of 75 metres based on its measurements of the quarry material. For this reason, it is better to describe 31,000 tonnes and 73 metres as commonly cited estimates for the intended assembled monument, rather than to present either figure as an absolutely precise modern measurement.

Why Was the Giant Stele Abandoned?
The most significant problem was not carving the stone. It was moving it. Once the enormous blocks had been cut from the mountain, transporting them to Ming Xiaoling and then raising them into position would have been an almost unimaginable engineering challenge for the early 15th century.
The stele body alone was roughly 49.4 metres long and weighed thousands of tonnes. The base was even heavier. Moving such blocks overland would have required a transportation system capable of handling loads far beyond anything practical with the technology and infrastructure available at the time. The planners eventually recognised that they could not realistically complete the monumental project.
Instead of attempting to move the enormous stones, the project was abandoned. The three components remained at Yangshan Quarry, where visitors can still see them today. That failure is actually what makes the site so fascinating. The quarry preserves the physical evidence of a project that reached an extraordinary stage of construction before practical reality brought it to an end.
The Smaller Stele at Ming Xiaoling
The Yongle Emperor's original plan eventually gave way to a much smaller monument. The Shengong Shengde Stele, meaning roughly “Divine Merits and Godly Virtues", was installed at Ming Xiaoling in 1413. It commemorated Zhu Yuanzhang but was dramatically smaller than the giant monument originally planned at Yangshan.
According to the Nanjing Zhongshan Mountain Scenic Area authority, the surviving Shengong Shengde Stele at Ming Xiaoling is 8.78 metres high, including its components and tortoise-shaped pedestal. The contrast is striking: the replacement monument is an impressive historical stele in its own right, but the original Yangshan project would have towered many times higher.

What Makes Yangshan Quarry So Remarkable?
Yangshan is unusual because the abandoned stones were not simply discarded blocks transported elsewhere. They remain connected to the landscape in which the project began. Visitors can see the enormous base, body and head as separate pieces, along with the marks left by centuries-old stoneworking. The quarry therefore functions almost like an open-air record of an unfinished construction project.
The site also illustrates an important lesson in ancient engineering. The Ming craftsmen were capable of cutting and shaping astonishingly large quantities of stone, but creating a monument was about more than quarrying. Transportation, lifting and assembly were equally important problems. At Yangshan, the scale of the ambition ultimately exceeded the practical limits of the project.

Inside the Sifangcheng (Square City) Pavilion at the Ming Xiaoling Mausoleum in Nanjing stands a remarkable stone bixi, a mythical tortoise-like creature traditionally associated with carrying monumental steles. On its back rests the Shengong Shengde (“Divine Merits and Godly Virtues”) stele, erected in 1413 by the Yongle Emperor in honour of his father, the Hongwu Emperor, the founder of the Ming dynasty. The enormous monument combines imperial history, traditional Chinese sculpture, and symbolism. The pavilion itself forms an impressive entrance monument within the Ming Xiaoling complex, making the bixi and stele one of Nanjing’s notable historical sights.

Yangshan Quarry Stele FAQs
How tall would the Yangshan Quarry Stele have been?
If the three major components had been finished and assembled as intended, the monument would have stood approximately 73 metres (240 feet) tall.
How much did the Yangshan Stele weigh?
The commonly cited combined estimate for the three unfinished components is more than 31,000 metric tonnes—about 31,167 tonnes using the frequently published component estimates.
Who ordered the Yangshan Quarry Stele?
The project was ordered by the Yongle Emperor, Zhu Di, in 1405 during the Ming dynasty. The monument was intended to honour his father, Zhu Yuanzhang.
Where is the Yangshan Quarry Stele?
The unfinished stele components are at Yangshan Quarry in Jiangning District, Nanjing, Jiangsu Province, China. The site is now part of the Yangshan Quarry Scenic Area.
Why was the Yangshan Stele never completed?
The enormous stones proved impractical to transport and install. After extensive quarrying, the project was abandoned, and the three components were left at Yangshan.
What are the three parts of the Yangshan Stele?
They are the stele base, stele body and stele head. They were carved separately because the finished monument was intended to be assembled at another location.
What replaced the unfinished Yangshan Stele?
A much smaller Shengong Shengde Stele was erected at Ming Xiaoling in 1413. It is about 8.78 metres high, including its pedestal.
Can the unfinished stele still be seen today?
Yes. The enormous carved components remain at Yangshan Quarry and form the central historical attraction of the Yangshan Quarry Scenic Area.

Conclusion
The Yangshan Quarry Stele is one of those rare historical monuments whose unfinished state is more fascinating than a completed structure might have been. In 1405, Ming China attempted to create an enormous imperial memorial from the limestone mountains outside Nanjing. The plan called for a monument about 73 metres tall, using three blocks whose combined commonly cited weight exceeded 31,000 metric tonnes.
The craftsmen succeeded in carving the gigantic stones. What they could not overcome was the problem of moving and assembling them. More than six centuries later, the three unfinished pieces still sit where craftsmen carved them. They stand as a remarkable reminder that even at the height of imperial power, some engineering ambitions were simply too large to carry from the quarry to the finished monument.
