Hong Kong has several Bronze Age rock carvings, plus others possibly Early Iron Age but still debated. Declared as monuments by the Government, these rock art sites are the only above-ground features left by the early population of the territory ca. 1000 B.C. Other rock art in Macau, Zhu Hai and the broader region is also described. In a presentation with 200+ slides, the dating and possible meaning of these mysterious patterns are discussed, along with the highly controversial conservation issue. Possible links with folk religious practices still surviving in Hong Kong are examined.
