The bell-shaped chedi on a mangrove island in the Rayong river, built as a landfall marker for boat crews and now the emblem of the province.

| Royal temple class | Not established from an official register. |

| Ancient monument | Registered national ancient monument Royal Gazette vol. 118, special part 124 ng, p. 6, 17 December B.E. 2544 Item 2 of an announcement covering Chonburi and Rayong only, signed on 20 August B.E. 2544 by Group Captain Awut Ngoenchuklin as Director-General and published nearly four months later, with site plans bound after it. The area was read by eye off the department's scan as 13 rai 69 square wa, matching the register exactly. A different announcement, covering four provinces, sits two pages earlier in the same part. |
| Coordinates | 12.666081, 101.241916 Fine Arts Department national ancient monument register (GIS), monument 0000809, independently corroborated by the ONEP cultural-environment register, which gives 12.6663 and 101.24184 for the same monument — the two points fall within about fifty meters of each other and both inside Tambon Pak Nam, Mueang Rayong |
Thai temple histories mix two different kinds of statement, and this guide keeps them apart. What a register, a gazette entry, an inscription or a dated royal act shows is one thing. What the chronicles and the temple itself hold is another, and it is worth telling as what it is.
The ONEP record does not hold together on the reign. It gives the building year as B.E. 2416 and, in a later paragraph, places the work in the reign of Rama IV, who died in B.E. 2411. The year falls in the reign of Rama V and the page never reconciles the two statements.
Before the Sukhumvit road reached this coast, the only comfortable way into Rayong was up the river. A crew coming in from the gulf needed to know when they had arrived, and the answer was built for them: a bell-shaped masonry chedi about ten meters tall on a low island in the river mouth, visible over the mangrove from well out. The cultural-environment register kept by ONEP dates the work to B.E. 2416, under the governor Phraya Si Samut Phokchai Chitsongkhram, whose personal name was Ket Yomchinda, and says the idea was borrowed openly from Phra Samut Chedi at Samut Prakan, which told officials traveling up to the capital that Bangkok was close. The Fine Arts Department's own description agrees that the two chedis resemble each other.
Its purpose has outlived its usefulness. Nobody navigates to Rayong by chedi any more, but the thing became the emblem of the province, and the devotional life around it has grown rather than faded. On the full moon of the twelfth lunar month, at Loi Krathong, the chedi is wrapped in red cloth. The tourism authority lists the cloth-draping as a fixture of the provincial calendar, run alongside the long-boat racing on the river. The ONEP record describes the ceremony closely enough to contradict itself about it, giving the length of the cloth as six meters in one paragraph and five in another, with two people climbing to drape the upper bell either way. Fishermen quoted on the same page put the point more simply: when you see the finial, you are home.
The island around the chedi is what the registration actually protects. The announcement of B.E. 2544 draws 13 rai 69 square wa around it — a figure that can be read off the department's own scan of the gazette page and that matches the register to the square wa. The ONEP record, measuring something else, describes the island as about fifty-two rai in one place and about fifty in another. Rayong City Municipality built the concrete bridge that crosses to it and maintains the ground, and the walk out through mangrove is now most of the reason people make the trip.
One point of method is worth recording here, because it would be easy to get wrong. The chedi's registration and Wat Ban Khai's sit in the same part of the Royal Gazette, vol. 118, special part 124 ng of 17 December B.E. 2544, and they are not the same instrument. Page 4 carries an announcement covering Chonburi, Rayong, Chachoengsao and Nakhon Nayok. Page 6 carries a separate announcement covering Chonburi and Rayong, signed on a different day, and the chedi is item 2 of that one. The department's register cites only the volume, part and publication date for both, so anyone who cites the first page for the chedi is wrong by two pages and will not be told so.
The chedi itself: a bell-form masonry structure the Fine Arts Department measures at about ten meters, standing on a circumambulation terrace with two flights of steps and a low surrounding wall, its base built as a row of pointed arched recesses.
The terrace balustrade, faced with pierced green-glazed tiles — the single detail that most clearly dates the work to the late nineteenth century rather than to anything older.
The mangrove island it stands on and the concrete bridge Rayong City Municipality laid across to it, which is how the site is reached on foot.
The stands of pine planted around the chedi, which the ONEP record notes and which make the island a place townspeople use in the evening rather than only a monument.
In the twelfth lunar month, the red cloth draped around the upper bell at Loi Krathong, with long-boat racing on the river beside it.
This is a working place of worship for millions of people rather than an attraction, and it is treated as one at the gate. Where a figure below is blank, no source we are prepared to cite states it.
| Hours | Not established from an official source. |
|---|---|
| Admission | Not established from an official source. |
| Dress | A place of devotion rather than a park. Dress as you would at a monastery if you intend to go up onto the terrace. |
| Photography | No source we found states a rule, so we print none. |
| Getting there | About two kilometers from the center of Rayong town: from Taksin Maharat Road turn into Samut Chedi Road and cross the concrete bridge the municipality built over the mangrove. |
Every temple reference repeats claims nobody has checked. These are the ones we went looking for and could not stand up, listed so you know exactly where this page stops.
No. It is a free-standing chedi on an island in the Rayong river, with no resident monks, registered as an ancient monument in its own right rather than as part of a monastery.
As a landfall marker. The ONEP register records that the governor of Rayong had it put up so that boat crews and passengers coming up the river would know they had reached the town, following the example of Phra Samut Chedi at Samut Prakan.
The Fine Arts Department describes it as a bell-form masonry chedi about ten meters high, on a circumambulation terrace with two stairs.
At Loi Krathong, on the full moon of the twelfth lunar month, red cloth is draped around the upper bell of the chedi, alongside long-boat racing on the river. The tourism authority carries it as an annual provincial event.
On foot, across the concrete bridge Rayong City Municipality built over the mangrove, about two kilometers from the town center by way of Samut Chedi Road.
Before you go, read the guide to Buddhism and temple etiquette in Thailand — dress, footwear, where photography is not welcome and how to behave around monks. The rest of Rayong’s temples are covered here too.
Every temple here sits in a place worth reading about on its own terms. The nationwide temple guide covers the other provinces to the same documentary standard as this page, and says on each one what the record establishes and what it does not.
If you are thinking about more than a visit: work out which Thai visa route fits your situation, and see what is available to rent and buy in residences across Thailand.
