Wat Phrathat Lanong / Wat Phra That Khlang Nam (Sunken Chedi)

Wat Phrathat Lanong, also known as Wat Phra That Khlang Nam or the Sunken Chedi, is one of the more unusual and evocative religious sites along the Mekong River in Nong Khai Province. The temple's ancient chedi partially submerged in the river is its defining feature — a result of the riverbank gradually eroding over centuries — lending the site a quietly dramatic quality that sets it apart from more conventional temple visits in the region.

Visitors come to pay respects at this historically significant site, which remains an active place of Buddhist veneration. The atmosphere is contemplative and unhurried, with the river providing a constant, calming backdrop. The sight of the chedi emerging from the water is particularly striking during the dry season when river levels are lower and more of the structure is visible, making seasonal timing worth considering when planning a visit.

The temple is open daily from 07:00 to 18:00, with no entrance fee specified, which is typical of many community temples in the area. As with all Buddhist temples in Thailand, visitors are expected to dress modestly, covering shoulders and knees. The site is located in Nong Khai's urban district, making it accessible in combination with other nearby attractions along the riverfront. Those travelling from Udon Thani can reach Nong Khai by bus or train in under an hour.
