Stone circle was discovered at Fan Lau, on Lantau Island in 1980. (22.1973°N 113.8473°E) It lies 40 metres (130 ft) above sea level.[2] This stone circle is a Declared monument in Hong Kong. The use of the stone circle is unknown, it was possibly used for rituals, or possibly not. It is assumed[by whom?] that it is a megalithic structure created during the late Neolithic (i.e. New Stone Age) and early Bronze Age.[1]
