Wat Yai Suwannaram — or just Wat Yai as locals call it — is a third-class royal temple of the worawihan rank, sitting in the middle of Phetchaburi's old town in Tha Rap subdistrict, a short walk in from the Phetchaburi River. It dates back to the Ayutthaya period and was given a major restoration in the time of Somdet Chao Taeng Mo (Phra Suwanmuni), a Phetchaburi-born monk who was a teacher of King Suea. What sets this temple apart from the average wat is that it works like a museum of Phetchaburi craftsmanship that's still in everyday use — not stuck behind glass.
The teak sermon hall — a royal audience hall moved here whole
The star of the temple is the sermon hall, built entirely of teak. It's a large Thai-style building with pakon panel walls and tiered, well-proportioned roofs. The story locals are proud of is that this hall was originally a royal audience hall in the Ayutthaya court, which King Suea ordered dismantled and given to Somdet Chao Taeng Mo, then reassembled here at the temple in full. That means every piece of woodwork came from royal craftsmen, not ordinary temple builders. Look up at the roof structure inside and you'll see how each timber is jointed together tightly with almost no nails.
- Teak pakon panels — walls built from grooved boards slotted together, high-level joinery that has held up for hundreds of years
- Columns and beams — large timbers mortised together in the old Thai house style, showing joinery that doesn't rely on nails
- Preaching pulpit — an Ayutthaya-era carved wooden pulpit finished in lacquer and gold leaf, standing in the hall, with extremely fine carving
Take it all in
A lot of people step into the hall, snap one wide shot, and leave. Take a moment to look up at the roof frame and walk over for a close look at the pulpit — the carving photographs better on a phone than you'd expect. The best light is mid-morning, before about 10am.

The carved doors — sword marks that are still there
If there's one spot worth stopping at for a while, it's the carved doors of the sermon hall. They're covered edge to edge in flowing scrollwork and floral motifs, the work of Phetchaburi craftsmen in the late Ayutthaya period — deep, layered carving that reads almost three-dimensional. But what makes these doors tell a bigger story than just their beauty are the marks left by a blade in the wood, said to come from a battle in the old days, when Burmese soldiers hacked at the doors with an axe or sword to get at people hiding inside. Those marks are still there today, which makes the doors both a work of art and a piece of historical evidence on the same panel.
To be straight with you, historians still debate whether it was really the Burmese or bandits from local legend — but whichever version you go with, the marks in the wood are real, and they're usually the first thing local guides point out. If you go with a temple or community guide, they can show you exactly where the marks are.
The ordination hall murals — assembled deities over 300 years old
Inside the ordination hall there's a tempera mural depicting the assembled deities — rows of devas seated with their palms pressed together, in Ayutthaya style, painted by genuine Phetchaburi craftsmen. The age of this set is backed by a royal note from King Rama V, who recorded that the murals in this ordination hall were painted more than 300 years earlier. Much of the color has faded with time, but the lines and composition still read clearly — a rare example of old Thai painting that survives in its original state.
- The assembled deities — rows of devas with palms pressed together around the walls; notice the faces and regalia that are distinctly Phetchaburi work
- Old tempera paint — made from natural pigments, so flash and touching the walls are strictly off-limits
- The principal Buddha image — a stucco Buddha image in the hall, finely made in the Ayutthaya style
Manners in the ordination hall
The ordination hall is sometimes closed or only open at set times. If you want to see the murals, ask a monk or staff member at the front of the temple first. Dress modestly, take off your shoes, no flash, and don't touch the walls — the old paint is very delicate.
The scripture library over water, and other corners
Walk a bit further and you'll reach the scripture library, or ho trai — a wooden building with pakon panel walls standing in the middle of a pond, raised on wooden posts. Building the library over water was an old piece of wisdom to keep ants and termites from reaching the manuscripts. It's another corner that photographs well and shows how the old craftsmen thought. Around the temple there are also big shade trees and a quiet, calm atmosphere that's good for a slow walk.

Hours, admission, and getting there
- Hours — daily, roughly 07:00–17:00 (the ordination hall may only open at certain times; ask at the front of the temple)
- Admission — free, no entry fee; you can make a donation if you wish
- Location — Tha Rap subdistrict, Mueang Phetchaburi district, in the old-town area near the Phetchaburi River
- Getting there — a few minutes by car or motorbike taxi from the town center; there's parking at the temple, and it's easy to keep exploring the old town on foot
- Time needed — about 45 minutes to 1 hour for a proper look
Wat Yai sits in the old-town area with plenty more to walk to nearby. Close by you'll find Wat Mahathat Worawihan with its striking white prang, along with Phetchaburi's old sweets shops and long-running curry-and-rice places. It all adds up to a tidy half-day trip exploring the city of craftsmen.
