Sala Kaeo Ku (Wat Khaek)

Sala Kaeo Ku — also written Sala Kaew Ku, and signed locally as Wat Khaek — is a concrete sculpture park on the Mekong riverside outskirts of Nong Khai, built not by a temple committee but by one man’s decades-long personal vision. Luang Pu Bunleua Sulilat, a self-taught spiritual teacher who mixed Hindu, Buddhist, and animist belief into his own syncretic philosophy, started construction here in 1978 after being forced out of Laos, where he’d built a similar park (Wat Xieng Khuan, still standing near Vientiane) on the opposite bank of the river. He directed the statues’ design according to his own visions until his death in 1996, and the park has continued largely as he left it.

The scale is the first thing that registers. More than 200 concrete sculptures fill the grounds, ranging from waist-high figures to the park’s largest works at around 25 metres tall — among them a seven-headed naga sheltering a meditating Buddha, the sculpture most visitors photograph on the way in. Hindu deities stand beside Buddhist figures without separation: Shiva, Vishnu, and Indra share the grounds with Buddha images in multiple postures, alongside animals, demons, and figures from folk stories that don’t map neatly onto either religion. Sulilat wasn’t illustrating scripture so much as building out his own cosmology in concrete, and the park reads that way — genuinely strange rather than merely decorative.

The centrepiece for many visitors is the Wheel of Life, a circular walk-through sculpture depicting the karmic cycle of birth, death, and rebirth. Visitors enter through a giant mouth at one point on the wheel and exit through a birth canal at another, passing scenes of heaven, hell, and everyday human life along the way — it’s built to be walked, not just viewed. Inside the main Sala Kaeo Ku pavilion, the third floor holds Bunleua Sulilat’s own mummified body in a glass case, kept alongside photographs and objects from his life. It’s an unusual thing to encounter in what’s ostensibly a tourist sculpture park, and it tends to leave a stronger impression than any single outdoor statue.

Locals and Thai visitors treat the grounds as consecrated space rather than a gallery — expect to see offerings of flowers, incense, and fruit at various shrines among the sculptures, and Thai visitors bowing before the Buddhist figures even as they walk past the more outlandish Hindu-derived works. That mix of genuine devotion and open strangeness is what distinguishes Sala Kaeo Ku from a typical roadside curiosity.

Insider Tip: Visit in the morning before 9am — the concrete surfaces have no shade and get uncomfortably hot to walk near by midday, and the low-angle light makes the taller statues easier to photograph without a washed-out sky behind them.

Watch out: Dress modestly (shoulders and knees covered) since parts of the site function as active shrines, and remove your shoes before entering the Sala Kaeo Ku pavilion itself, including the floor with the mummified body.

The park sits on the Nong Khai–Bueng Kan road, a short drive from central Nong Khai. Combine it with Wat Pho Chai, home of the town’s most revered Buddha image, or Ta Sadet Market along the Mekong riverfront for a full day around Nong Khai’s mix of the sacred and the offbeat.
