Yangpu Ancient Salt Field

The Yangpu Ancient Salt Field (simplified Chinese: 洋浦千年古盐田; traditional Chinese: 洋浦千年古鹽田; pinyin: Yángpǔ qiānnián gǔ yántián) is an archeological heritage site in Yantian village, on the Yangpu Peninsula in Hainan, China.

The area comprises more than 1,000 stones, cut flat on top, which are used to evaporate seawater to produce salt.

During low tide, this evaporates, leaving the salt, which is then collected.

The area was established around 800 AD[2][3] when a group of salt workers from Putian city in Fujian province moved to Yangpu.

[1] Today, only a small group of villagers continue to make salt using this method and it is not their main source of income.

Stones are cut flat on top with a thin rim. Seawater remains from high tide. It then evaporates leaving the salt, which is collected.
