Prasat Yai Ngao

Prasat Yai Ngao is a small Khmer sanctuary in Ban Chop subdistrict, Sangkha district, built in the first half of the 12th century during the reign of King Suryavarman II — the same era, and broadly the same architectural style, as Angkor Wat. Three brick prangs stand on a stone platform along a north-south axis. Entry is free, and unlike Surin’s more visited sites, you’ll likely have the ruins to yourself.

Experience

Of the three towers, only two were substantially built. The central prang keeps its base and reliquary chamber, though the upper structure has collapsed. The southern prang is the best preserved of the group, with three tiers still visible above the platform. The northern tower survives only as a brick-and-stone foundation — most likely abandoned before it was finished. A square brick wall originally encircled the whole complex.

The standout detail is on the southern tower: a naga carved directly into the brick in bas-relief, extending onto the gable end above the doorway. Most Khmer sanctuaries carve nagas into sandstone lintels rather than the brick body of the tower itself, which makes this an unusual — and rarely photographed — technique for a site this size. The entrance itself is framed by a five-headed naga motif.

Insider Tip: Walk around to the south side of the central tower for the clearest view of the brick-carved naga — it’s easy to miss if you only approach from the front.

Atmosphere & Timing

There’s no ticket booth, no gift shop, and usually no other visitors. Rice paddies surround the ruins on most sides, and the quiet is broken mostly by birdsong and the occasional motorbike on the approach road. Local legend holds that the sanctuary’s name — Yai Ngao, “lonely grandmother” — comes from a folk tale about a woman who left the third tower unfinished while waiting for her husband to return from war. It’s a story told locally rather than a documented part of the site’s history, but it’s worth asking about if you run into anyone tending the grounds.

Watch out: There’s no shade shelter and no water on site. Bring your own water and wear shoes that can handle uneven, sometimes overgrown ground around the northern foundation.

Practical

The site is in Ban Chop, roughly 50 km from Surin town along Road No. 24 toward Sangkha, reachable by car or motorbike. There’s no public transport directly to the site, so your own transport or a hired driver is the practical option. For nearby Khmer ruins in the same district, Phumpon Castle is close by, and Prasat Hin Ban Phluang makes a reasonable add-on further north in Prasat district. The Surin Province hub has more on planning a wider Khmer-ruins route through the region.
