Three Pools Mirroring the Moon
Located in the heart of Hangzhou’s West Lake, Three Pools Mirroring the Moon (San Tan Yin Yue) is one of China’s most iconic landscapes and a UNESCO World Heritage Site. Comprising three small islets with five-meter-tall stone towers pierced with moon-shaped holes, this scenic spot is famed for its ethereal beauty, especially during autumn evenings when the moon’s reflection shimmers across the water. Built in the Southern Song Dynasty (1127–1279) and later renovated during the Qing Dynasty, the site blends natural harmony with poetic symbolism, representing the legendary “Three Pools Reflecting the Moon” from Chinese folklore.
Historical Overview
Constructed over 800 years ago, the islets were originally designed as a hydraulic project to regulate water levels in West Lake. Legend attributes their creation to a mythical battle between a dragon and a phoenix, while historical records emphasize their role in irrigation and flood control. During the Qing Dynasty, Emperor Qianlong added the moon-shaped towers, transforming the site into a cultural symbol of lunar harmony. The towers’ hollow centers were ingeniously designed to hold candles, creating a mesmerizing “moonlight” effect on the water’s surface at night.

Structural Layout
The three islets form a triangular arrangement in West Lake’s Outer Lake:
- Xiaoyingzhou (Little Yinzhou Island): The northernmost islet, featuring a pavilion and the tallest stone tower.
- Huixin Ting (Heart-to-Heart Pavilion): The central islet, connected by a causeway to the shore.
- Ruan Gong Dun (Lord Ruan’s Mound): The southernmost islet, named after a Tang Dynasty official who dredged West Lake.
Each islet is surrounded by lotus ponds and willow-lined shores, with the stone towers standing as sentinels of ancient craftsmanship.
Major Attractions
- Stone Moon Towers: The five-meter towers, each with five moon-shaped holes, create a magical play of light and shadow during full moons.
- Heart-to-Heart Pavilion: A classical pavilion offering panoramic views of West Lake and the islets.
- Lotus Ponds: Seasonal blooms of pink and white lotuses frame the islets, symbolizing purity.
- Ancient Causeways: Stone pathways linking the islets to the mainland, ideal for leisurely strolls.
- Mythical Sculptures: Carvings of dragons and phoenixes on the towers reflect traditional Chinese cosmology.
