Wat Phra That Chom Ping

Wat Phra That Chom Ping sits in Na Kaeo subdistrict, Ko Kha district, about 10 kilometres from Lampang’s most famous temple, Wat Phra That Lampang Luang. It was built during the reign of King Tilokarat, the Lanna king who also founded Lampang Luang in the mid-15th century, and the two temples share that era’s architecture and status as historic pilgrimage sites. Entry is free, and the temple is open daily from 08:00 to 18:00.

The temple’s gold chedi rises about 34 metres, its stepped, multi-cornered base and gilded surface showing the Lanna style with a Burmese touch — not unusual in this part of Lampang, where craftsmen from across the border worked on temples for centuries. But the chedi’s real claim to fame isn’t its height or gold leaf; it’s what happens inside a small hall beside it.

Insider Tip: Ask which side building houses the pinhole image before you arrive — there’s no signage pointing to it from the main chedi, and it’s easy to walk straight past.

Wat Phra That Chom Ping is one of only four temples in Lampang province where this happens: light passing through a small hole in a window or door shutter projects a full-colour, upside-down image of the golden chedi onto a white cloth stretched inside a darkened room — a natural camera obscura effect. Locals treat it as close to miraculous; photographers treat it as one of the more unusual sights in northern Thailand. The image is reportedly sharper in the afternoon, when the sun angle favours the room, though you’re dependent on the shutter being closed down to a single hole and the room properly darkened.

Watch out: if the room isn’t set up — shutter closed to a pinhole, interior darkened — there’s nothing to see beyond the exterior chedi. It’s worth asking a caretaker before assuming the phenomenon is on display.

Outside the pinhole room, the grounds keep a quiet, working-temple pace: a modest ordination hall, a scattering of Buddha images, and local worshippers making offerings rather than coach tours passing through. Dress modestly and remove your shoes before entering any building. Treat this as a half-day stop combined with Wat Phra That Lampang Luang and Wat Akkho Chai Khiri — the other Lampang temple with the same inverted-image effect — or Wat Phrathat Lampang Luang itself, about 15 minutes away by car.
