Wat Phra Kaew

WatBuddhist monastic complex that brings together, within a single enclosure, several religious buildings, monks’ quarters and ancillary buildings; the word does not refer to a single building. Phra Kaew occupies the north-eastern corner of the Grand Palace, on Rattanakosin Island in Bangkok. It is not a single, isolated building but a group of buildings, brought together within one enclosure and arranged around a single imageIn Thai Buddhism, a devotional representation of the Buddha, most often a statue, venerated as an object of worship., the Emerald Buddha. It is this statue that gives the place its common name.⁴

Yet Wat Phra Kaew is not a monastery in the usual sense. No monks or nuns live there, and it is not their principal place of assembly. It was formerly the private chapel of the kings and the court.²

The temple’s official name is Wat Phra Si Rattana Satsadaram; Wat Phra Kaew is merely a shortened form that has passed into common use. The same name is borne by other temples in the country, in Chiang RaiThai unit of land area, equivalent to 1,600 square metres., Kamphaeng Phet and Phetchaburi, which should not be confused with the Bangkok sanctuary. One of them, in Chiang Rai, is bound up with the very history of the image.⁴

The Emerald Buddha also has two Thai names: Phra Kaeo Morakot in everyday use, and Phra Phuttha Maha Mani Rattana Patimakon as its ceremonial name. Despite its name, it contains no emerald. The statue owes this name to its green colour, that of a hard stone whose exact nature is still debated.¹⁰

The Emerald Buddha is an image of the Buddha seated in meditation, of modest size. Where, when and by whom it was carved is unknown. Even its material divides specialists: jade and jasper have been suggested, and one hypothesis sees it instead as a jadeite from northern Thailand or from the Shan State, in present-day Myanmar.³

The question of where it was made remains open. Some scholars, drawing on the doctoral thesis of the art historian Melody Rod-ari, place its creation in the region of Chiang Rai and Chiang Saen, in the far north of the country. This hypothesis would link the image to the kingdom in which it first appears, but nothing allows it to be taken as established.¹³

The image enters history in 1434, in the kingdom of Lan Na. In Chiang Rai, lightning strikes a chediA bell-shaped reliquary monument, the Thai version of the Indian stupa., a reliquaryA container intended to hold and protect one or more relics. monument, at Wat Pa Yia, and reveals a statue covered in stucco. The abbot removes this coating and discovers a figure carved from a green semi-precious stone. The temple then takes the name Wat Phra Kaew. A legend adds that the image is said to have been carried off in 1432, then hidden in Chiang Rai before its discovery.¹⁴

In 1436 King Samfangkaen, then ruling Lan Na, has the image brought to his capital, Chiang Mai. According to tradition, the elephant carrying it refuses this route and of its own accord takes the road to Lampang. This is received as a divine sign: the image remains in Lampang, in a temple built for it, the present-day Wat Phra Kaeo Don Tao. It stays there for some thirty years.³

King Setthathirath, ruler of Lan Xang, the neighbouring Lao kingdom, later seizes the image and makes it his personal palladium, that is, the sacred object that protects his person and his power. The statue then resides in Vientiane.¹⁰

It is in Vientiane that, at the end of the 18th century, it is recovered by General Chakri, then in the service of King Taksin, who reigns from Thonburi. Taksin keeps the image for about five years, from 1779 to 1784, at Wat Jaeng, the present-day Wat Arun. Over three and a half centuries, the Emerald Buddha thus passed from Lan Na to Lan Xang and then to the Siamese kingdom.¹

After Taksin is deposed, General Chakri becomes king under the name Rama I and founds a new dynasty. He establishes his capital, Krung Rattanakosin, today Bangkok. There he has the Grand Palace built and, within its precincts, Wat Phra Si Rattana Satsadaram, where he installs the Emerald Buddha.¹

This transfer is not simply the moving of an object. By installing the image within the precincts of his palace, Rama I marks the beginning of his reign. Temple, palace and capital are born together. The king also links the place to the memory of his family: he has two gilded chedis raised there in memory of his parents.²

Work begins in 1782 and is completed in 1783. The consecration takes place in 1785, with the solemn transfer of the image into the ubosotConsecrated ordination hall of a wat: the ritually central building, marked out by sacred boundary stones, where monastic ordinations take place., the ordinationCeremony by which a layperson is admitted as a novice or as a monk into the Buddhist community. hall, at the beginning of that year. These stages span the very first years of the reign of Rama I, when the temple rises at the same time as the capital.¹⁰

Half a century after the founding, King Rama III has the whole complex restored to mark the fiftieth anniversary of the Chakri dynasty. Most of the murals visible today date from his reign.²

At the end of the reign of Rama IV, a further restoration is accompanied by the construction of additional shrines. The Ho Phra Ghandharat pavilion is then raised at the front corner of the ubosot’s cloister.¹²

The heart of Wat Phra Kaew is the Phra Ubosot, the ordination hall that houses the Emerald Buddha. The image does not rest on a simple altar: it is set high up, beneath a busabokThai throne in the form of a small pavilion, covered by a tapering spired roof., a gilded pavilion topped by a spire, in the form of a prasatIn Thai architecture, a building or canopy with tiered roofs crowned by a spire, a form reserved for sacred images and for royalty., a building with a tiered roofRoof made up of several superimposed, stepped sections, characteristic of traditional religious and royal architecture in Thailand., here of five levels.²

It is up to this busabok that the king climbs, several times a year, to change its regalia.⁶

To the north of the ubosot, a raised platform lines up several major buildings from west to east. The Phra Si Rattana Chedi, the largest chedi in the temple, opens the sequence. Next comes the Phra MondopSmall sacred building or pavilion, often square in plan, which may house a sacred image, a Buddha footprint, relics, scriptures, ashes or another sacred object., a square pavilion whose northern stairway is guarded by sculptures of demons. The Prasat Phra Thep Bidon houses statues of the kings of the Rattanakosin periodPeriod of Thai history that began with the founding of Bangkok as the capital by King Rama I at the end of the eighteenth century. It takes its name from Rattanakosin Island, the heart of the royal city.. The two gilded chedis raised by Rama I for his parents complete this alignment.⁴

This platform thus brings together Buddhist veneration and the cult of the royal line. Other monuments within the precincts are dedicated to former Chakri kings, and the Phra Wihan Yot adds to the complex’s shrines. The temple also includes several pavilions and a belfry whose bell rings only on rare occasions, such as the announcement of a new Supreme PatriarchHead of the Buddhist monastic community of Thailand, appointed by the king., head of the country’s monastic community.⁴

The cloister surrounding the complex is covered with murals devoted to the RamakienThai version of the Ramayana, the Indian epic of the hero Rama., the Thai version of the RamayanaGreat Sanskrit epic of India recounting Prince Rama’s struggle against the king of the demons; it has inspired many versions in Southeast Asia, including the Thai Ramakien., the Indian epic of Prince Rama. The cycle unfolds in 178 sections. It begins near the front of the Phra Wihan Yot and runs right round the cloister, so that visitors follow the epic as they walk.⁵

These paintings date back to the reign of Rama I, but they have been restored and repainted on several occasions. Those of the Rama III period largely follow the style and themes of the first campaign, which explains why much of the present painting belongs to that reign without breaking with the original programme. The gallery is today among the main points of interest for visitors, and the whole is regarded as a major testimony to Thai craftsmanship since the late 18th century.⁵

The most visible rite at Wat Phra Kaew is the changing of the Emerald Buddha’s regalia, performed three times a year, at the turn of the hot season, the rainy season and the cool season. The ceremony, a royal rite, is presided over by the king in person.⁶

The ceremony follows a precise order. The king climbs up to the busabok, removes the crown of the season that is ending, purifies the image with lustral water, a consecrated water, and then places the new crown. Brahmins, officiants of the royal rites of Hindu origin, conclude the ceremony with the Wien ThienThai rite of circumambulation: a procession around a sanctuary or venerated object, holding candles, incense and flowers, keeping it on one’s right., a circumambulation, a procession around the sanctuary, by candlelight. The king then sprinkles holy water over the officials and the public gathered outside. Today King Maha Vajiralongkorn (Rama X) performs this rite with Queen Suthida, as in July 2026.⁶

Other royal ceremonies long centred on a second image, the Phra Ghandharat, also called Phra Kho Fon, the ‘Buddha who asks for rain’. Kept in the Ho Phra Ghandharat pavilion built under Rama IV, this statue was the principal imageIn a Thai Buddhist monastery, the most important statue of the Buddha, around which worship is organised; it is generally installed in the monastery’s main building. of the royal rain ceremony and of the Royal Ploughing CeremonyThai royal ceremony of Brahmanical origin, held each year to open the agricultural season and foretell the harvest, combined with Buddhist rites., which opens the agricultural season. This practice is traced back to the reign of Rama I.¹²

Finally, the Emerald Buddha is a solemn witness. According to a traditional practice, politicians accused of corruption come to swear their innocence before the image.³

Wat Phra Kaew remains an active royal place of worship, where the seasonal rites continue to be celebrated. It comes under the Bureau of the Royal Household, which also manages the Grand Palace. A single ticket gives access to the palace, the temple and the Queen Sirikit Museum of Textiles; the site is open every day, and admission is free for Thais on presentation of their identity card.¹¹

This dual role as royal sanctuary and visited monument shapes the experience of the place. Visitor numbers fell sharply when mass tourism came to a halt, around 2020. The courtyards and the gallery then regained an unaccustomed calm.⁴

The image’s journey has left its mark on the cities that received it. In Chiang Rai, where the statue had appeared in 1434, a replica of the Emerald Buddha was consecrated in 1991 at the city’s Wat Phra Kaew. In Lampang, Wat Phra Kaeo Don Tao recalls the years when the image was kept there.¹³

These places make the Emerald Buddha a figure shared by several regions and several former kingdoms. Wat Phra Kaew in Bangkok is its point of arrival and its royal sanctuary; but the story it holds begins elsewhere, in the north, and is also told through the temples that preserve the memory of its passing.
