The Hangzhou City Wall was the city wall that once surrounded Hangzhou during the medieval and early modern periods of imperial China. Despite being the most populous city in the world during the Song and early Yuan dynasties, the historic city was much smaller than the borders of the present Hangzhou Municipality and only surrounded the districts immediately east of West Lake in the present city's urban core. The walls were largely dismantled in the early 20th century and what remains has largely been rebuilt and maintained as tourist attractions, but they were a significant part of Hangzhou's historical urban identity and the wall's course and gates are still evidenced by many aspects of modern Hangzhou's design and place names.
History
Hangzhou was first made a prefectural capital near the end of the Southern Chen dynasty, immediately before its conquest by the Sui. The Sui renamed the prefecture but maintained its organization, erecting Hangzhou's first city walls in the 11th year of the Wen Emperor. Its perimeter at the time was reported as 36li and 90 paces. The course of this wall was roughly along Zhonghe Road on the east, turning west on the north end at about the location of Hangzhou's No. 6 Park, turning south near the eastern shore of West Lake, and turning back east along the northern slopes of Phoenix Hill. Wu Hill was excluded by an indent in the course of the wall.Under the Qing, the city wall was high and wide across the top. It restricted views of West Lake to "Chenghuang Hill", the era's name for Wu Hill, and the three western gates. 7000 mu of the central city were also separately walled off to create a Manchu district and banner garrison; this wall was high and had 5 gates of its own in addition to the Qiantang Gate. Litters passing through the Manchu gates were routinely searched, prompting most Han residents and visitors to use the other 2 western gates to access the lake. During the Taiping occupation of Hangzhou in the early 1860s, the city walls trapped the residents and allowed the Qing army to restrict supplies during their siege, leading to an estimated 600,000 deaths.
The walls of the Manchu garrison were demolished in 1912.
Present condition
In 1994, Hangzhou erected memorial plaques at the locations of the Qing city wall's ten main gates: Wulin Gate, Genshan Gate, Fengshan Gate, Qingtai Gate, Wangjiang Gate, Houchao Gate, Qingbo Gate, Yongjin Gate, Qiantang Gate, and Qingchun Gate.The reconstructed Qingchun Gate now serves as the Hangzhou Ancient City Wall Museum or Exhibition Hall, located at 1 Qingchun Road. It opened on 4 February 2008 after two years of rebuilding and now covers an area of. The wall was restored to its Qing size and style but with a Song-era fortification atop the wall.
The Fengshan Water Gate has also been maintained and refurbished as part of the Grand Canal World Heritage sites, owing to its importance guarding the connection between the Jiangnan Canal with the Qiantang River and East Zhejiang Canal beyond. It is one of two Chinese water gates thus given international protected status, along with the Panmen Gate in Suzhou.
