Wat Tong Pu

An ancient Buddha-bathing fountain — described locally as the only surviving example of its kind in Thailand — sits within the grounds of Wat Tong Pu, tucked behind Phibun Wittayalai School in Lop Buri. It’s a quieter, less-visited counterpart to the city’s famous Khmer ruins, and the fountain alone makes it worth the detour.

The temple’s name comes from the Mon word for a troop-gathering place; oral history holds that Thai forces mustered here during the Ayutthaya period, which explains a name that has nothing to do with religious practice. The vihara’s pointed-arch windows and doorways are a style associated with the reign of King Narai the Great in the mid-17th century, when Lop Buri functioned as a second royal capital alongside Ayutthaya — though no inscription confirms an exact founding date. Beyond the vihara, the grounds hold an ordination hall with a distinctive curved base, a single ancient chedi, a scripture hall, and a bell tower, laid out in the compact style typical of temples from that era.

Insider Tip: Ask at the temple office (or call ahead) about the Buddha-bathing fountain if you can’t immediately spot it — it’s a smaller, easy-to-miss feature compared with the vihara and chedi, and staff are usually happy to point visitors toward it.

Wat Tong Pu draws a fraction of the crowds that Lop Buri’s headline sites — Phra Prang Sam Yot and its monkey-populated towers, or Phra Narai Ratchaniwet — pull in daily, which makes it a good stop if you want Ayutthaya-period architecture without the tour-bus traffic. The site is compact enough to see properly in 20-30 minutes. Shade is limited across the open grounds, so a midday visit in the hot season gets uncomfortable fast; aim for morning or late afternoon instead.

Watch out: As with any active temple, cover shoulders and knees and remove shoes before entering the vihara or ordination hall — this remains consecrated ground, not just a historical ruin, even though the site reads as quiet and archaeological.

Getting there is easiest by bicycle or motorbike from central Lop Buri — a handful of kilometres, well within range of a rented bike — and the temple pairs naturally with a wider loop of the city’s Ayutthaya-era sites if you’re spending a full day on Lop Buri’s history rather than just its famous monkey temple.
