Every year during dry season when the water is low, a sunken Buddhist stupa emerges from the Mekong River in Nong Khai province. A piece of an ancient temple that slipped off the bank of the river more than 150 years ago, the chedi is believed to be more than six centuries old.
Despite being submerged most of the time, the Wat Phra That Khlang Nam is deeply revered by Buddhist communities in Thailand and Laos, and is said to contain original Buddha relics. Every time the stupa becomes visible, locals hold a special stupa worship festival.
Many people make a boat pilgrimage to pay homage to the shrine. To make it more easily spotted by fishermen, the upper tip of the stupa is wrapped in yellow fabric.
