Big Wave Bay Rock Carving, Ancient petroglyph at Big Wave Bay, Hong Kong CN.

Big Wave Bay Rock Carving is a 90 cm by 80 cm abstract geometric pattern carved into a coastal cliff at Big Wave Bay, east of Shek O on Hong Kong Island. The carving is now enclosed in a protective cover.

A police officer discovered this rock carving by chance in 1970, which led to its official protection. Hong Kong designated it as a declared monument in 1978 to preserve this ancient artwork for future generations.

The carvings are abstract bird-and-beast motifs arranged in roughly geometric forms, not fish. Archaeologists estimate they were cut in the Neolithic period, and the local belief was that such carvings protected seafarers, expressing worship of navigation and astronomy.

The site is open to visitors but protective barriers keep people at a safe distance to prevent damage to the ancient carving. Visit in good weather and wear suitable footwear, as the coastal headland can be rocky and uneven.

This carving is one of only a handful of rock petroglyphs found along Hong Kong's coast. The exact age of the artwork remains uncertain, making it intriguing for both researchers and visitors.
