The ruins of Helv City , the capital of the Wu Kingdom, are an extremely precious historical and cultural heritage site in Wuxi. It was the capital of the Wu Kingdom, one of the Five Hegemons of the Spring and Autumn period. The city was first built in the first year of Helu's reign (the sixth year of King Jing of Zhou, 514 BC), and has a history of over 2500 years.

Helv City was the capital city of the 24th ruler of the Wu Kingdom, King Helv of Wu. Helv was a hero of the late Spring and Autumn period. In 515 BC, he ordered the warrior Zhuan Zhu to assassinate his cousin, King Liao of Wu, with the Yu Chang sword and ascended to the throne. He recruited talents, valued the livelihood of the people, was strict with himself, and diligently governed, enabling the rapid rise of the Wu Kingdom. He also adopted Wu Zixu's suggestion to "build city walls, set up defenses, fill granaries, and govern armories,"
