Palace of Prolonging Happiness: The Unfinished Hall
The Palace of Prolonging Happiness, or Yanxi Gong, is known for the unfinished Lingzhao Xuan structure. A fire and later rebuilding plan gave this eastern court a form unlike the neighboring residences.
- Chinese name: 延禧宫 / Yanxi Gong.
- Area: Six Eastern Palaces.
- Signature sight: unfinished Lingzhao Xuan, sometimes called the Water Palace.

How Do You Find the Structure?
Follow the Palace Museum’s central route from Meridian Gate toward the inner court. Take the signed eastern-palace branch to 延禧宫. The gate guide helps you return north.
View Lingzhao Xuan only from the current visitor line. Its exposed form draws attention, but the unfinished building is not an invitation to enter or climb.
What Tickets and Opening Times Apply?
This court is inside the Palace Museum, so begin with museum admission. Courtyard access can change during stabilization, exhibitions or safety work. Nearby eastern palaces may remain open when this one is closed.
Check the museum route for your date. The name “Water Palace” does not mean there is a working pool or a separate water attraction to book.
What Is Different About Yanxi Gong?
The court was a residence before a fire changed its buildings. A later plan for Lingzhao Xuan drew on materials and ideas unlike the usual timber halls. Work stopped before the planned structure was finished.
Look at the exposed framework beside neighboring rooflines. The contrast makes the building sequence easy to grasp. The architecture guide explains the broader timber and courtyard pattern.
When and How Long Is Enough?
Allow a brief eastern-court stop after the main halls. Stay longer only if the court is open and you want to compare the structure with adjacent residences. Keep time for the northward exit.
An overcast sky can soften glare on the exposed frame. Rain, wind or maintenance may move the viewing line farther back. Take the view available that day.
What Common Mistakes Should You Avoid?
Do not describe Lingzhao Xuan as a completed imperial swimming pool. It was an unfinished rebuilding project, and its nickname can mislead. The earlier residence and later project belong to different phases.
Do not cross a barrier for a close photo. This is an exposed historic structure, and the marked distance is part of the visit.
FAQ: What Should You Know?
Is Lingzhao Xuan complete? No. The planned structure was left unfinished. Its surviving frame is the main visual feature.
Can visitors enter the Water Palace? Do not plan to enter the structure. View it from the currently marked public area.
Is Yanxi Gong on the main central route? No. It is in the eastern palace group. Add a short branch and return to the northbound path.
