The Long Corridor was originally built in the 15th year of Emperor Qianlong’s reign (1750) and then rebuilt in the 12th year of Emperor Guangxu’s reign (1886) because the Anglo-French Allied Forces burned it down in 1860. It starts from Inviting the Moon Gate in the east and ends at Shizhang Pavilion in the west, covering a distance of 728 meters with its 273 sections. Of all the corridors in Chinese classical gardens, the Long Corridor is the longest. On the beams are more than 8,000 colorful paintings depicting stories from Chinese classical novels, folk tales, landscapes as well as flora and fauna. Four pavilions, “Mesmerizing Scenery”, “Harmonizing with the Lake”, “Autumn Water” and “Clear and Carefree”, with octahedral structures and double eaves, were built intermittently along the corridor. Taking the Hall that Dispels the Clouds as the center, the Long Corridor stretches symmetrically to the east and the west along the foot of the hill and the water bank, linking all the structures scattered along the Longevity Hill side into a whole.
