Archaeologists recently discovered more than 100 stone carvings on a high mountain in the northern Ha Giang province.
The carvings, believed to date back to the 10th century AD and made spontaneously on large stones with metal tools, comprise symbolic circles, spirals, rectangular patterns and parallel lines, besides triangles symbolising the female reproductive organs.
The carvings are two types – to mark the area and to reflect sexual meanings – according to researcher Trinh Nang Chung from the Viet Nam Archaeology Institute.
The stone carvings were found in Ho Quang Phin, Dong Van district in Ha Giang province. Scientists will further examine the site to get more information about the early people who made the carvings.
