Wat Phra Si Rattana Mahathat Ancient Remains

Ancient brick foundations and a tall Khmer-style prang mark one of Sukhothai province’s major temple sites — though not inside Sukhothai’s own historical park. Wat Phra Si Rattana Mahathat stands at Chaliang, on a bend of the Yom River just outside Si Satchanalai, roughly 50 km north of Sukhothai Historical Park, and it served the Sukhothai Kingdom’s secondary city rather than its capital. Three separate Thai temples carry the name Wat Phra Si Rattana Mahathat — a royal title meaning “temple of the great relic” — so this one is easily confused with the Lop Buri temple of the same name and with Wat Yai in Phitsanulok.

Unlike most of the ruins scattered around Si Satchanalai, this is still a working temple layered over an archaeological site — Mon, Khmer, and Thai styles sit side by side across the grounds. The central prang, restored and still standing, rises over the ruined outline of the original ordination hall, where rows of column bases mark where seated Buddha images once faced worshippers. Weathered lotus-bud stupas and partial brick walls surround the main structure, their cores exposed by centuries of monsoon rain.

Insider Tip: Most day-trippers stop only at the walled central zone of Si Satchanalai Historical Park and skip Chaliang entirely because it’s a separate ticket. It’s worth the extra 20 THB — this is widely considered the most complete single site in the area.

The grounds see far fewer visitors than the main historical park, which makes for a quieter walk among the ruins even in high season. Birds nest in the crumbling walls and grass has reclaimed old temple courtyards, but the site is still tended as an active place of worship, not an abandoned one.

Bring sun protection and water. Traditional temple dress codes are relaxed for the ruined areas, but the site remains active for worship, so keep footwear off any raised platforms with Buddha images and stay respectful around them.
