Phon Nha
Phong Nha lies amid the limestone mountains of central Vietnam, where the Son River emerges from a great cave. Underground streams have carved passages and chambers through the karst, while forest covers the rugged slopes above. The cave was known to the people of Champa: inscriptions and clay votive objects found within it point to religious activity associated with Avalokitesvara in the ninth century. Its dark chambers preserve a remarkable trace of a sacred landscape extending beyond Champa's brick temples.
