As the winter solstice approaches, Beijing's Summer Palace witnesses its annual celestial spectacle at the Seventeen-Arch Bridge. This 18th-century architectural marvel, stretching 150 meters across Kunming Lake, becomes bathed in golden light each sunset this week as sunlight aligns perfectly through its namesake arches.
The phenomenon, occurring only during December's shortest days, draws photographers and history enthusiasts alike. "This alignment showcases our ancestors' profound understanding of astronomy and geometry," explains cultural heritage researcher Dr. Li Wei. "The bridge's orientation was precisely calculated during Emperor Qianlong's reign to create this winter light show."
Visitors this year can enjoy extended viewing hours until December 25, with the palace remaining open until 7:00 PM. Park authorities have implemented crowd management measures to ensure safe viewing while preserving the UNESCO World Heritage Site's integrity.
