圆明园
The Old Summer Palace before October 1860

Three gardens, one residence: a model built from evidence.
The palace north-west of Beijing was made up of three gardens: 圆明园 Yuanming Yuan, "Garden of Perfect Brightness"; 长春园 Changchun Yuan, "Garden of Eternal Spring"; and 绮春园 Qichun Yuan, "Garden of Elegant Spring".
Building began under the Kangxi Emperor in the early 1700s, and the Yongzheng and Qianlong Emperors enlarged it. From Qianlong on it was the main imperial residence, where the emperors handled state affairs. The Forbidden City was used for formal ceremonies.
Most of it was Chinese: halls, lakes and hills arranged as scenes. Along the back of Changchun Yuan stood a small group of European-style palaces, 西洋楼 Xiyang Lou, begun in 1747, designed by the Jesuit Giuseppe Castiglione, with fountains by Michel Benoist.
What you see here is reconstructed, not surveyed. Every building carries its sources and a grade, A, B or C, and where the evidence runs out we guess and say so.

Why just before October 1860.
We rebuild the gardens as they stood in the last years of the Xianfeng reign, just before their destruction. The album of 1744 and the copperplates of the 1780s count for that state wherever nothing later contradicts them.
Our base is a large Qing plan of the gardens that draws every hall by its bays, in a state of the Daoguang and Xianfeng reigns. It gives the positions and footprints; the paintings, engravings, texts and digs give the rest.
- 1707–09The Kangxi Emperor grants the land to Prince Yinzhen, the later Yongzheng Emperor.
- 1725Yongzheng builds the audience hall and offices on the south side.
- 1744The Forty Scenes are named and painted.
- 1747Work begins on the European palaces in Changchun Yuan.
- 1770–74Qichun Yuan joins the gardens.
- 1855The last dated addition we have found: the theatre of 同道堂 Tongdao Tang.
The gardens, as painted and as our model pictures them.
The first pictures are period evidence: leaves of the 1744 album and the copperplates of the 1780s. The pictures after them are AI pictures made from our 3D model, not evidence: each one says so, says what the AI added, and has a small map of where it looks from.
Engraved and painted while the gardens stood.

Our model, held against the copperplate.
Drag the divider. On the left, our 3D model of 大水法 Dashuifa, the Great Fountain, seen through the camera we fitted to plate 15, with the plate's taller heights allowed for. On the right, the plate itself. The engraver idealised, and our model guesses where nothing survives: across the plate the fit is 1.42 m (root mean square), worst where the plate shortens the court.

October 1860.
During the Second Opium War, British and French troops looted the palace and British troops burned it.
- 6 OctoberFrench and British troops captured the palace.
- 7–9 OctoberBoth armies looted it. The Forty Scenes album was among what was taken; it is now in the Bibliothèque nationale de France.
- 18–19 OctoberLord Elgin, the British High Commissioner, ordered its destruction, in retaliation for the torture and execution of prisoners held by the Qing. British troops under General Sir James Hope Grant burned most of it. The French commander refused to take part.
Today the site is a public park in Haidian District. The ruins of the European-style palaces are its most prominent remains, and lakes and waterways in the eastern half have been dug out and refilled.
西洋楼 Xiyang Lou, what the ruins hold.
The ruins that everyone knows from the Old Summer Palace are these: a strip of European-style palaces and fountains, built for the Qianlong Emperor from 1747 with Jesuit designers and Chinese craftsmen. We have gone through them building by building: the engravings, the photographs of the ruins then and now, what is known of their sizes, what survives and where the fragments are.

Halls, lakes and hills, one scene at a time.
Outside the European palaces, the gardens were Chinese halls and courts set round lakes and hills. For each scene and compound we have gathered what the album of 1744, the Qing texts and plans, the excavations and today's site say about it, and what is known of its size, so that it can be modelled.

Not an empty plain: gardens, camps, villages.
The gardens stood among other imperial gardens, the camps of the banner guard, the market town of 海淀 Haidian, villages and rice fields fed by the springs of the Jade Spring hills. We have gathered what the Qing texts, the accounts of 1860 and the old maps say about that ring, and put a first, labelled version of it round the gardens in the 3D view. Most of it is inferred, and the page says how sure each part is.

Every building traced to a source.
Qing site plans give positions and footprints. The Forty Scenes album and the Xiyang Lou engravings of the 1780s give forms, roofs, trees and bridges. Today's lakes, islands and hills tie the old plans to the ground.
Every feature carries its source and a grade. Where the evidence runs out we guess, and say so.
- AShown on a source made while the gardens stood, or measured on remains that survive unchanged.
- BA later source: photographs of the ruins, 20th-century surveys, modern scholarly reconstructions, or a written description only.
- CInferred from typology or symmetry. Every guess is a C.
Do you have a photograph, a plan, a text?
Most halls are still drawn from their class, not from their own evidence. A photograph, a plan or a text that gives a size can turn a guess into a graded fact.
