Wat Prayoon
A white riverside chedi in Thonburi with an artificial mountain of grottoes and a turtle pond at its foot.
Updated 28 August 2026
Wat Prayoon sits on the Thonburi bank where Memorial Bridge crosses, and it has two distinct parts. The white chedi, Phra Borommathat Maha Chedi, is a large bell-shaped stupa in Sri Lankan style built in the 1830s; a restoration completed in 2013 won a UNESCO Asia-Pacific award, and an inner gallery around the base holds small stupas and relics. The other part is Khao Mo, an artificial hill built of stacked rock and cement into a landscape of miniature grottoes, shrines, bridges and model buildings around a pond - a nineteenth-century Thai garden form representing a mythical mountain, and one of the better surviving examples. The pond is full of turtles, and buying food for them is the standard visit; the turtles are a mixture of native and released pet species, and the population is large enough that the temple periodically has to manage it. The Portuguese-founded Santa Cruz church is a short walk along the same bank.
Highlights
- The white chedi - the 1830s stupa, restored to a UNESCO award in 2013.
- Khao Mo - the artificial rock mountain of grottoes and shrines.
- The turtle pond - large numbers of turtles, fed by visitors.
- The riverside position - at the Thonburi foot of Memorial Bridge.
When to go
November to February. It is quiet compared with the Phra Nakhon temples. An hour covers it, and it combines with a riverside walk to Santa Cruz church and Kudi Chin.
Things to know
Free but donations are pressed at several points. The turtle population is partly released pets and overfeeding is a problem. Temple dress code applies. Small - an hour is enough.
Nearby
Santa Cruz church and the Kudi Chin Portuguese quarter are along the bank; Wat Arun is upriver.
