A bridge leads from the island of the Beihai Park to the Circular City, surrounded by walls with a height of 4 meters and a circumference of 277 meters. This highly original construction is composed of spectacular rooms, towers and pavilions, and the most important building is the Chengguang Temple, with a marvelous white jade statue of Buddha imported from Burma towards the end of the Qing dynasty. Opposite is a large dark jade urn with a diameter of one and a half meters and a height of 70 cm, which was used to store wine.
