The Forbidden City, also known as the Purple Forbidden City, served as the imperial palace of the Ming and Qing dynasties, where emperors lived and conducted state affairs. Stepping into the Forbidden City, you enter a world that is both real and mysterious, where you can experience the unique charm of imperial life and Chinese culture. In 1987, it was inscribed on the UNESCO World Heritage List.

If you only have limited time in Beijing, the Forbidden City is almost the one historical site you cannot miss. It is not just a palace, but a key gateway to understanding five hundred years of Chinese imperial history and civilization.

1. The Mystery Behind the Name

The name “Forbidden City” itself is full of mystery, like a key that opens the world of ancient Chinese imperial power and cosmology.

“Purple” refers to the Purple Star, also known as the North Star. In ancient Chinese astrology, this star was believed to be the residence of the Heavenly Emperor, governing the order of the universe and human destiny. The emperor was regarded as the “Son of Heaven,” as his supreme authority was granted by heaven. The Forbidden City was therefore seen as an earthly reflection of the Purple Forbidden Enclosure, symbolizing the emperor’s absolute power on earth. Standing within the palace, you can sense the ancient reverence for the relationship between heaven and imperial authority—an atmosphere unmatched by any other palace.

“Forbidden” refers to strict security control. Except for the emperor, members of the royal family, and eunuchs, no one was allowed to enter without permission. The heavily guarded gates made the Forbidden City long shrouded in an atmosphere of mystery and solemnity.

“City” originally refers to city walls or defensive structures, which are an important facility in ancient architecture to protect the core area. In the Forbidden City, it not only surrounds the emperor's residence, but also symbolizes the solemnity and inviolability of imperial power. The entire palace is like a huge "castle", reflecting the emperor's supreme authority and the noble status of the royal family.

Today, the Forbidden City is also known as the “Palace Museum,” meaning “the former imperial palace.” Its museum collections contain countless treasures, each carrying centuries of history, allowing visitors to step into a world full of legendary imperial heritage.

2. Why the Forbidden City Is Worth Visiting

As a UNESCO World Heritage Site, the Palace Museum is not only one of China’s most important historical and cultural landmarks, but also a heritage shared and protected by all humanity.

The Forbidden City has witnessed the historical changes of China for more than 500 years and is an important window for understanding the ancient Chinese imperial power system, palace culture and traditional architectural art. The red walls, yellow tiles, layers of palaces, exquisitely carved beams and columns, and detailed and solemn dragon pattern decoration all show the grandeur and unique aesthetics of ancient Chinese royal architecture.

When you pass through the Meridian Gate and step onto the vast stone-paved courtyard, the unfolding palace complex makes you truly understand the meaning of the “Imperial City”—it is not just architecture, but a spatial expression of imperial order.

3. Historical Overview

The Forbidden City is located at the very center of Beijing. It served as the imperial residence and political center for 24 emperors of the Ming Dynasty (1368–1644) and Qing Dynasty (1644–1911). Construction began in 1406 during the reign of Emperor Yongle of the Ming Dynasty and was completed in 1420, representing the finest example of ancient Chinese palace architecture.

The complex underwent fires, restorations, and major expansions during the Kangxi and Qianlong reigns, reaching its peak scale. During the Republican era, it was converted into the Palace Museum and opened to the public. After the founding of the People’s Republic of China, it underwent extensive restoration and conservation. In 1961, it was designated a National Key Cultural Relic Protection Unit, and in 1987 it became a UNESCO World Heritage Site.

Today, the Palace Museum receives millions of visitors every year and uses digital technologies to preserve and present its collections, bringing ancient history into a more modern form.

4. Architectural Structure

The central axis

The Palace Museum is one of the largest and best-preserved ancient palace complexes in the world. Its layout is built around a strict north–south central axis, reflecting traditional Chinese cosmology in which the emperor is regarded as the center of heaven and earth. This highly symmetrical design expresses the principle of “centrality” and imperial authority.

This spatial order is further reinforced by traditional Chinese feng shui principles, particularly the ideas of “facing south” and “central supremacy,” which emphasize harmony between the ruler, the built environment, and the cosmos.

The complex is divided into two main sections: the Outer Court and the Inner Court. The Outer Court, centered on the Hall of Supreme Harmony, was used for major state ceremonies, while the Inner Court, centered on the Palace of Heavenly Purity and the Palace of Earthly Tranquility, served as the emperor’s residence and the imperial household. A popular saying describes the palace as having “9,999 and a half rooms,” symbolizing supreme imperial authority.

The entire complex is surrounded by massive walls and a moat, with four main gates. The north–south central axis extends from the Meridian Gate to the Gate of Divine Might, passing through the entire palace city.

Its architectural features are defined by three key elements: symmetrical axial layout, traditional wooden mortise-and-tenon construction, and red-and-yellow color symbolism. Together, these create a unified and highly symbolic imperial architectural system.
