Diaoyucheng

Diaoyucheng stands on a mountain five kilometres east of the Hechuan urban area, on the south bank of the Jialing, on a peninsula thrown out where the Jialing and Qu rivers loop together. The ancient fortress covers 2.94 square kilometres. It was built in Southern Song times and resisted the Mongols for thirty-six years through more than two hundred confrontations between 1243 and 1279. It was named a national key cultural relic protection unit in 1996 and placed on the tentative World Heritage list in 2018.
