A collection of 18 Buddhist arhats carved directly into a cave wall nearly 800 years ago in Ninh Binh Province, northern Vietnam, has been recognized as a National Treasure.
The carvings are the only known collection in Vietnam depicting 18 Buddhist arhats carved directly into a natural rock face.
For almost eight centuries, the 18 arhat figures have remained on the rock walls of Lien Hoa Cave within Phong Phu Pagoda in Tay Hoa Lu Ward.
Despite centuries of exposure to time and natural conditions, most of the carvings remain relatively well preserved.
The collection was created during the Tran Dynasty, a period when Buddhism flourished in Dai Viet, the historical name of the Vietnamese state at the time.
What makes the work particularly distinctive is that the figures were carved directly into natural rock, a form of cliff and cave inscription art known in Vietnam as ma nhai.
