Forbidden City: Inside the World's Most Valuable Palace Complex

The Forbidden City is the world’s most valuable palace complex, estimated at $70 billion. It covers 720,000 square metres, contains 980 buildings with 8,728 rooms, and was home to 24 emperors across six centuries. For most of that time, entering without permission was punishable by death. Today it receives roughly 19 million visitors per year.

The Yongle Emperor’s Vision

The Forbidden City was ordered by Zhu Di, the Yongle Emperor, who had seized power in 1402 by overthrowing his nephew. He needed a new capital to consolidate his legitimacy, and he chose Beijing — moving the imperial centre north from Nanjing. The palace that would anchor his capital had to be unprecedented.

Construction ran from 1406 to 1420. One million labourers were mobilised, including 100,000 specialised craftsmen. Materials were sourced from across China: enormous stone slabs from quarries near Beijing, timber from forests in Yunnan and Sichuan, bricks fired in special kilns in Shandong. The Phoebe Zhennan wood used for major structural elements — now valued at approximately $10,000 per cubic metre — was sourced from forests that were essentially clear-cut to supply the project.

The Language of Architecture

Every element of the Forbidden City’s design carries meaning. The number nine — the highest single digit and associated with imperial power — appears throughout. Door studs come in rows of nine, totalling 81 per door. Yellow roof tiles indicate imperial buildings; green indicates princes. The spatial arrangement — with the most sacred spaces at the north, progressively more accessible spaces toward the south — maps the hierarchy of the imperial world.

The complex is oriented precisely along the north-south axis. The central spine of ceremonial halls aligns with the meridian of Beijing. The spatial order is not aesthetic preference; it is cosmological assertion.

Six Centuries of Crisis

The Forbidden City’s survival across 600 years required weathering repeated catastrophes.

In 1421, just one year after completion, lightning struck three major halls and burned them to the ground. Reconstruction took years. In 1626, the Wanggongchang Armory — a weapons depot at the city’s edge — exploded catastrophically. Over 20,000 people died in Beijing. Two thousand workers on Forbidden City rooftops were killed by the shockwave. The explosion’s cause has never been definitively established.

British and French forces occupied the complex in 1860 during the Second Opium War, looting it extensively. In 1900, foreign forces returned during the Boxer Rebellion.

The Last Emperor

Puyi became Emperor of China at age two in 1908, following the death of the Guangxu Emperor. When the Qing Dynasty collapsed in 1912, he abdicated but was permitted to remain in the northern portion of the Forbidden City. His world shrank to those buildings. In 1924, a coup expelled him permanently. He was 18 years old and had spent his entire conscious life behind those walls.

Survival During the Cultural Revolution

The Forbidden City’s most remarkable survival came between 1966 and 1976. The Cultural Revolution targeted everything the palace represented — imperial hierarchy, Confucian tradition, historical continuity, elite culture. Red Guards destroyed monuments and temples across China.

The Forbidden City was protected. Soldiers sealed the gates on direct orders, preventing the destruction that was consuming China’s cultural heritage elsewhere. The reasons remain debated — perhaps it was too famous, too internationally visible, too useful as a symbol of China’s civilisational depth. Whatever the reason, the decision preserved one of the world’s irreplaceable architectural complexes.
