In the center of Beijing stands a city within a city —72 hectares of golden roofs, red walls, and marble terraces, surrounded by a 52-meter-wide moat. For 500 years, this was the center of the Chinese universe. Emperors were born here, ruled from here, and died here. No commoner could enter without invitation. No foreigner saw its interior until the 20th century.

This is the Forbidden City (Zijin Cheng / 紫禁城）, the largest palace complex ever built. And every element of its design was calculated to express absolute power.

The Cosmic Layout

The Forbidden City’s design is not arbitrary. It is a three-dimensional model of the cosmos as understood by Ming dynasty cosmologists:

North-South axis: The entire complex is aligned on a perfect north-south axis, representing the axis mundi —the connection between heaven and earth. This axis continues through Tiananmen Gate, the Meridian Gate, and northward to Jingshan Park’s artificial hill.

The Outer Court (Yang): The southern half, where emperors conducted public ceremonies and received officials. Wide, open spaces; massive buildings; overwhelming scale. This was the masculine, active, public face of power.

The Inner Court (Yin): The northern half, where the emperor lived with his family, concubines, and eunuchs. Smaller buildings; more intimate courtyards; greater privacy. This was the feminine, receptive, private realm.

The color red: Symbolizing fire, joy, and the south. Every wall is red.

The color yellow: Imperial monopoly. Every roof is golden-yellow glazed tile.

The number nine: The emperor’s number. The complex has 9,999.5 rooms (by traditional count). Door studs appear in multiples of nine. The main gates have 81 (9×9) studs.

Construction: An Empire’s Resources

The Yongle Emperor (reigned 1402–1424) ordered the Forbidden City’s construction after moving China’s capital from Nanjing to Beijing. The project consumed the empire:

  • Labor: 1 million workers including soldiers, peasants (conscripted for seasonal labor), and specialized artisans
  • Artisans: 100,000 craftsmen —carpenters, stonemasons, tile makers, painters, gilders, and bronze casters
  • Time: 14 years of continuous construction (1406–1420)
  • Materials: Timber from southwestern China’s forests; marble quarried near Beijing; “gold brick” paving made from specially fired clay in Suzhou
  • Cost: Unknown, but certainly a significant portion of imperial revenue

Many workers died. The marble ramps leading to the main halls were so massive that legendary accounts claim water was poured on ice roads in winter to slide the stones into position.

Key Buildings and Their Functions

The Meridian Gate (Wu Men)

The main southern entrance. Massive and imposing, it set the psychological tone: you are entering the center of power. Executions were sometimes carried out in the plaza before this gate.

The Hall of Supreme Harmony (Taihe Dian)

The largest building, raised on a three-tiered marble terrace. Here the emperor:

  • Ascended the throne on New Year’s Day
  • Received foreign ambassadors
  • Proclaimed edicts
  • Celebrated major victories

The interior throne sits beneath a coffered ceiling with a dragon surrounded by xuanwu —symbolizing the emperor as the pole star around which everything revolves.

The Hall of Central Harmony (Zhonghe Dian)

A smaller hall where the emperor rested and prepared before ceremonies. It contains his traveling throne.

The Hall of Preserving Harmony (Baohe Dian)

Where the final stage of the imperial examination was held —the top scholars kneeling before the emperor. The enormous marble ramp behind the hall, carved with dragons among waves, was too heavy for the front stairs; it was slid into place on an ice road, according to legend.

The Palace of Heavenly Purity (Qianqing Gong)

The emperor’s primary residence in the Inner Court. The “First Room Under Heaven.”

The Hall of Union (Jiaotai Dian)

Between the emperor’s and empress’s palaces, symbolizing the union of yin and yang, male and female.

The Palace of Earthly Tranquility (Kunning Gong)

The empress’s official residence. Later converted to a shamanistic shrine under the Qing.

Life Inside the Walls

The Forbidden City was a city —not just a palace. Its population included:

  • The emperor: Often isolated, surrounded by ritual and protocol
  • The empress and concubines: Living in luxurious confinement, competing for the emperor’s attention
  • Eunuchs: Castrated male servants who managed palace operations; their numbers reached 70,000 in some periods
  • Palace ladies: Maids, attendants, and female officials
  • Guards: Military units protecting the perimeter
  • Artisans: Carpenters, cooks, doctors, and specialists serving the court’s needs

Life was governed by incomprehensible ritual. Every movement, every meal, every garment was prescribed by tradition. The emperor’s daily schedule was determined by astronomers and diviners.

From Palace to Museum

The last emperor, Puyi, was expelled from the Forbidden City in 1924. In 1925, it became the Palace Museum —a public institution displaying China’s imperial collections.

The transformation was traumatic. Centuries of accumulated treasures were:

  • Shipped to Taiwan in 1948–1949 (now in the National Palace Museum, Taipei)
  • Redistributed to other Chinese museums
  • Sold or lost during wars and political upheavals
  • Preserved and displayed in Beijing

Today, the Palace Museum holds approximately 1.8 million artifacts —paintings, ceramics, bronzes, jade, furniture, textiles, and documents. It is the most visited museum in the world, with over 17 million visitors annually.

Visiting the Forbidden City

Practical advice for visitors:

  • Book tickets in advance: Online reservation is mandatory and dates sell out
  • Enter through the Meridian Gate: The traditional imperial entrance
  • Allow a full day: Rushing through defeats the purpose
  • Visit side halls: The main axis is crowded; the eastern and western wings contain fascinating exhibitions
  • See the gardens: The Imperial Garden at the north end offers relative tranquility
  • Exit through the Gate of Divine Might: And climb Jingshan for the classic aerial view

The Forbidden City is not merely architecture. It is power made visible —every stone, every color, every proportion calculated to overwhelm the individual and exalt the state. Standing in the Hall of Supreme Harmony, you understand why emperors believed themselves sons of heaven.

The architecture convinced them. It still convinces.
