A single Khmer prasat inside a square laterite-walled city on the Khwae Noi, built in the Bayon manner of Jayavarman VII's reign and — unusually for a Khmer monument in Thailand — Mahayana Buddhist rather than Hindu. It is the westernmost Khmer site in the country and the first place in Thailand the Fine Arts Department opened as a historical park.

Kanchanaburi is province 1 in that list and เมืองสิงห์ is item 4 of six, registered as being in อำเภอเมือง ตำบลแม่กระบาด, an address that no longer describes it. No land boundary was fixed then. One was fixed twenty-four years later by a further ประกาศกรมศิลปากร เรื่อง กำหนดจำนวนโบราณสถานสำหรับชาติ at เล่ม ๗๗ ตอนที่ ๖๐ หน้า ๑๗๔๖, published 19 July B.E. 2503 and signed 29 June B.E. 2503 by Dhanit Yupho as Director-General, which was also read by eye here: it names เมืองสิงห์ ตำบลสิงห์ กิ่งอำเภอไทรโยค, describes what is protected as the city wall and the antiquities inside it, and gives the area as ๗๑๘ ไร่ ๓ งาน with a plan attached. The department's own park history adds a third figure that neither instrument contains: the หนังสือสำคัญสำหรับที่หลวง the Land Department subsequently issued, received by the department on 17 August B.E. 2505, covers 641 rai 1 ngan 65 square wa — about 77 rai less than the gazetted boundary. |

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.
No founding date for this sanctuary is established by any document. What is established is a style, a set of excavated objects, and a chain of dated administrative acts from B.E. 2478 onward. The city's later life is separately recorded: the register says Mueang Sing was left abandoned after Khmer power receded, does not appear at all in the Ayutthaya-period roll of provincial ranks, was re-established as a small frontier post under King Rama I, had its governor titled Phra Saming Sing Burin by King Mongkut, and was reduced to a subdistrict under the monthon reforms of King Chulalongkorn.
Mueang Sing stands in Tambon Sing, Amphoe Sai Yok, on flat ground on the north bank of the Khwae Noi about 43 kilometres west of Kanchanaburi town. The city is a rectangle of roughly a square kilometre — the Tourism Authority of Thailand says rather more than 1.28 square kilometres, the Fine Arts Department's park history says about one, and the two figures are printed here rather than averaged. Its wall is built of laterite with an earth ramp banked against the inside face, and beyond it are moats and earthen ramparts: three surviving lines to the east and north, seven to the west. Six ponds lie inside the wall. The river runs along the southern side and was evidently meant to serve as the defence there.
What makes the place matter is not its size — the department is blunt that this was never a large city, because everything found in it is small — but its position and its religion. It is the furthest west any Khmer-culture monument stands in Thailand. And the sculpture excavated from it is Mahayana Buddhist: Avalokitesvara, a Buddha sheltered by a naga, Prajnaparamita, and a great many fired-clay votive tablets. That combination, a Bayon-period sanctuary at the western edge of the Khmer world with Mahayana images in it, is the whole argument for Mueang Sing.
The dating rests on style rather than on any dated text found at the site. The register puts the prasat at about the eighteenth Buddhist century, contemporary with the reign of Jayavarman VII, and the department's park history says the same. The Tourism Authority of Thailand's page for the site says the late Lopburi period, roughly the sixteenth to eighteenth Buddhist centuries. Neither reading rests on an inscription from Mueang Sing itself, because none has been found there.
The temptation is to close the gap with the Preah Khan inscription in Cambodia, which lists twenty-three cities where an image of the Jayabuddhamahanatha was installed, six of them read as central-Thai places — Lavodayapura for Lopburi, Suvarnapura for Suphanburi, Sri Jayarajapuri for Ratchaburi, Jayavajrapuri for Phetchaburi, and Sri Jayasinghapuri, which is where Mueang Sing comes in. The department's park history asserts the identification outright. The department's national register, on the same monument, says it cannot yet be concluded. A reader should know that both sentences are the state's.
Long before any of that, people were living on this stretch of river. Excavation outside the south wall found four prehistoric burials; two are still in the pit under cover and two were lifted and taken to the Ban Kao National Museum because their age and sex could not be determined and burrowing animals had disturbed them. The two that remain are both women, one about 30 to 35 and one about 20 to 30, buried with bronze vessels, agate and carnelian beads and glass beads. The department reads the material as late Metal Age and comparable to Ban Don Ta Phet in Phanom Thuan, and says plainly that no evidence has been found connecting that population to the people who later built the city.
The city's documented life afterwards is administrative and rather deflating. The register says no governor was appointed here in the Ayutthaya period and Mueang Sing does not appear in the roll of provincial ranks at all, so it was presumably left empty once Khmer power receded. King Rama I re-established it as a small frontier post reporting to Kanchanaburi, though the register notes the country was hard enough that the governor did not live here — he stayed at Ban Pong and sent patrols. King Mongkut gave the governors of the small Khwae Noi frontier towns new titles, and Mueang Sing's became Phra Saming Sing Burin. Under King Chulalongkorn's monthon reforms it was demoted to a subdistrict, which is what Tambon Sing still is.
The modern chapter is dated precisely because it is administrative. Registered in B.E. 2478 without a boundary; bounded at 718 rai 3 ngan by the order of B.E. 2503; a land title for 641 rai 1 ngan 65 square wa received in B.E. 2505; clearing, excavation and restoration begun in B.E. 2517; and formally opened as a historical park on 3 April B.E. 2530 by Princess Maha Chakri Sirindhorn, in the year of King Bhumibol's sixtieth birthday. The department's own history says it was the first historical park in Thailand. BAANLYY does not represent the park and nothing here is legal or religious advice.
Monument 1, the prasat itself, 227 metres in from the eastern city gate. You reach it across a cross-shaped laterite terrace whose rim is cut with a shallow groove about a foot wide — the department reads that as the seating for a naga balustrade that was either never finished or has gone entirely.
The gallery wall around the prasat: 81.20 metres across, 97.60 metres around, mostly collapsed but with whole stretches still standing, with gate openings in the middle of the east and west sides.
Inside it, a laterite court 23.60 by 25.60 metres laid out as three raised walkways crossing in a cross, leaving four shallow sunken panels 1.60 by 2.00 metres and 15 centimetres deep, ringed by 34 or 35 square postholes that the department reads as supports for a roof over the walkway.
The cloister and its four gopura. The east and west sides run about 36.40 metres, the north and south about 42.50. The north and south gopura are down to their bases; the western one is the most complete, with a three-tiered crown above the body and an amalaka finial cut into flower-petal lobes.
The central prasat on a redented square base 13.20 metres across, with porches on all four sides and a longer one to the east, standing on three tiers of moulding. The upper body and the whole tower above it have gone. Inside, on the north side, a lustration channel carries water poured over the image out through the wall to a basin at the north-eastern corner of the base.
The bannalai — the small rectangular building, 2.50 by 5.50 metres, at the south-east corner of the inner court, with one real door to the west, a false door to the east, and four small light slots in each of the north and south walls.
Monument 2, outside the north-west corner of monument 1: a group of six buildings on one shared two-tier platform, the lower step 33.90 by 54.20 metres. The department notes that this group is visibly out of true — the redenting on the east gopura differs side to side, the south gallery base is not straight where the north one is, the north gopura has a side stair and the south one has none — and reads that as either unfinished work or later addition. This is where the Avalokitesvara, the naga-sheltered Buddha and the Prajnaparamita came from.
Monument 3, 150 metres to the south-west: a small brick-and-laterite structure with stone slabs set at its outer corners like boundary markers, which yielded a large number of lead-alloy votive tablets. The department records a suggestion that it is older than the prasat.
Monument 4, 236.50 metres west of monument 1: four laterite floor compartments in a row, each 3.90 by 6.65 metres, with river gravel and packed sand — read as building foundations, with a sandstone sculpture pedestal found at the north end.
The prehistoric burial pit outside the south wall, roofed and left open, with two skeletons still in position.
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 | Open daily 07.30–16.30, per the Tourism Authority of Thailand's page for the park, read in a rendering browser on 8 September 2026. |
|---|---|
| Admission | Thai nationals: 20 baht. Foreign visitors: 100 baht. |
| Dress | An archaeological site rather than a working temple, so no ordination-hall dress rule applies. It is still a religious monument and shoes stay on the paths rather than on the masonry. Shade is thin and the site is walked, not driven. |
| Photography | No source we found states a rule, so we print none. |
| Getting there | Tambon Sing, Amphoe Sai Yok, Kanchanaburi 71150 — about 43 kilometres west of Kanchanaburi town on the north bank of the Khwae Noi. The Fine Arts Department gives the park office at 034 670264-5 and hp_muangsing@finearts.go.th; the Tourism Authority also lists 0 3452 8456-7. Car park and toilets on site. The department publishes a six-point self-guided route and two-dimensional codes at the monuments in English and Chinese as well as Thai. |
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, and this is the most common error made about it. Most Khmer-culture monuments in Thailand began as Hindu sanctuaries, but every state source that describes the religion of this one calls it Mahayana Buddhist. The Fine Arts Department's national register says so in terms, on the evidence of the architecture, the sculpture and the objects recovered by excavation, and the sculpture found at monument 2 is Avalokitesvara, a Buddha sheltered by a naga, and Prajnaparamita, together with a great many fired-clay votive tablets. It is a Buddhist site of a different tradition and a different century from the wats elsewhere in this guide.
Two arms of the Thai state give different answers and this page gives both. The Fine Arts Department's register and its own park history put the sanctuary at about the eighteenth Buddhist century, in the Khmer Bayon style associated with the reign of Jayavarman VII. The Tourism Authority of Thailand's page for the same site gives the late Lopburi period, about the sixteenth to eighteenth Buddhist centuries. No dated inscription has been found at Mueang Sing itself, so both readings rest on style rather than on a document, and no founding year for the sanctuary is established.
Yes. The Tourism Authority of Thailand's page for the park, read in a rendering browser for this page, gives admission of 20 baht for Thai nationals and 100 baht for foreign visitors, and opening hours of 07.30 to 16.30 daily. Its own structured fee field shows only the 20-baht figure, so the prose is the fuller statement. The Fine Arts Department, which runs the park, publishes contact details and a self-guided route on its site but no admission figure.
That is what the Fine Arts Department says on its own site for the park. Restoration and landscaping work began in B.E. 2517, and the department describes deciding to push the work through in time for the celebrations of King Bhumibol's sixtieth birthday year. Mueang Sing was formally opened on 3 April B.E. 2530 by Princess Maha Chakri Sirindhorn, and the department's history calls it the first historical park in Thailand. The claim is the department's own and it is repeated here as such.
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 Kanchanaburi’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.
