Palace of Prolonging Happiness: The Unfinished Crystal Dream of Beijing’s Forbidden City
Explore the enigmatic story, architectural vision, and eventual fate of the Palace of Prolonging Happiness—Forbidden City’s most unique and unfinished legacy.

Palace of Prolonging Happiness: An Architectural Tale of Vision and Memory
The Palace of Prolonging Happiness (Yanxi Gong) stands as one of the most compelling stories in Beijing’s Forbidden City. From imperial residence to an ambitious, unfinished architectural project known as the “Crystal Palace,” Yanxi Gong’s legacy is one of serenity, ambition, destruction, and ongoing fascination among historians and visitors alike.
Location and Historical Context
The Palace of Prolonging Happiness occupies a prominent spot in the southeast of the Forbidden City’s inner court. It is closely neighbored by the Palace of Eternal Harmony (Yonghegong) to the north and lies east of the Palace of Great Benevolence (Jingrengong), forming part of the prestigious “Six Eastern Palaces.” This cluster historically housed imperial consorts and concubines, illustrating the intricacies of palace life and the spatial hierarchy within the vast Forbidden City.
- Constructed: 1420, Ming Dynasty
- Function: Residence for imperial wives and consorts
- Part of: The Six Eastern Palaces
- Surroundings: South of Palace of Eternal Harmony, east of Palace of Benevolence
The Original Palace: Elegance and Daily Life
Initially, Yanxi Gong mirrored the architectural elegance of its neighboring palaces, with traditional Chinese courtyards, woodwork, and imperial embellishments. For centuries—from 1420 until the mid-19th century—it served as the home for imperial concubines, enveloped in ceremonies and protocols that defined the world behind the crimson walls of the Forbidden City.
Palace Life Highlights
- Residential quarters: Provided living spaces and retreats for favored concubines
- Cultural significance: Played a role in court rituals, daily routines, and palace intrigue
- Ming and Qing eras: Witnessed changes in residence patterns and imperial customs
Destruction: The Fire of 1845
In 1845, a devastating fire consumed most of the Palace of Prolonging Happiness. Only the main entrance survived the blaze. The destruction marked the end of an era for Yanxi Gong, transforming the once vibrant residence into a site of ruins and memories.
- Date of fire: 1845
- Extent of damage: Destruction of main buildings, survival of the front gate
- Aftermath: Years of dilapidation, dashed plans for restoration
The Crystal Palace Project: A Visionary Transformation (1909–1911)
The early 20th century saw an audacious attempt to resurrect Yanxi Gong in a radically new form—the Crystal Palace. Inspired by Western architectural styles and the legendary Crystal Palace in London, Qing officials unveiled plans for a three-storey pavilion built on a white marble base. The blueprint called for glass-paneled walls and floors, with water-filled interlayers to nurture fish, plants, and aquatic life—a living spectacle surrounded by four hexagonal pavilions and elegant verandas.
Key Features of the Crystal Palace Design
- Western influence: Marked shift from traditional Chinese design to European architectural vision
- Structure: Three floors, nine rooms per floor, surrounded by hexagonal pavilions and verandas
- Materials: Glass panes, steel pillars (with dragon motifs), porcelain tiles, and white marble
- Central basin: Water-filled canals designed for cultivating fish and aquatic plants
Ambitions and Reality: Abandonment and Legacy
Despite its bold vision, the Crystal Palace construction was doomed by technical limitations and lack of funds. The glass panel innovation proved unfeasible, and fiscal challenges halted building in 1911, leaving a marble skeleton and architectural fragments that stood as a haunting testament to the ambitions of a fading dynasty.
Modern Era: Exhibition and Research Centers
In the 20th and 21st centuries, the Palace site transitioned to other uses. Following the founding of the Palace Museum, Yanxi Gong’s east and central buildings were rebuilt to house research and exhibitions:
- 1931: Construction of three two-storey warehouses for artifact storage
- 2005: Establishment of the Research Center for Traditional Calligraphy and Paintings, Ceramic Research Center, and Ceramic Laboratory on the premises
- Current status: Yanxi Gong hosts exhibitions featuring overseas cultural relics, merging history with modern scholarship
