Tiger Hill Park(Chinese:虎丘；pinyin:hǔqiū) , the 'Leaning Tower of China' , comprises several historic and cultural relics to see, including Tomb of King He Lu, Yunyan Pagoda, Sword-testing Stone, the Thousand Men Rock, and the Sword Pond. The millennium-old Tiger Hill Yunyan pagoda stands on the top of the hill and is considered as the symbol of Suzhou. Known also as Surging Sea Hill, many of these historic helices on Tiger Hill can be traced back over 2,500 years to the time when Suzhou was initially founded.
