In the last days before Khao Phansa, the candle communities of Ubon Ratchathani work through the night. In the temple workshops the master carvers bend over towers of beeswax ten metres long, cutting the Buddha's lives into the surface, pressing moulded patterns onto the flanks, building naga and garuda out of softened wax while the neighbourhood brings food and watches. Then, on the morning of the holy day, the towers are hauled through the streets on trucks, with drummers and dancers alongside, seventy processions and more, to the great field at the centre of the city, Thung Si Mueang, where they stand floodlit for weeks. In 2026 the festival marks its hundred and twenty-fifth year, with the grand processions on 29 and 30 July and the candles on display from mid-July to mid-August. It is among the most beautiful things Thailand makes, and it is worth the journey to Isan on its own.
It is also younger than it looks, more official than it feels, and built on ground that holds more history than the festival tells.
What Toem Saw
The standard account comes from Toem Wiphakphotjanakit, whose History of Isan remains the foundational reference. Before 1901, he writes, there were no great communal candles at all: households moulded small tapers by village and took them to the temple, and in the countryside people simply offered what candles and incense they could find. Then, in 1901, Prince Sanphasitthiprasong, younger brother of King Chulalongkorn and the crown's viceregal commissioner for the Isan provinces, resident at Ubon, organised the city's temples into something new. The townspeople were to mould large candles together on the full moon of the eighth month; at four in the afternoon the candles were brought to the monthon government hall; through the night the town celebrated with molam singers, pipat and khaen ensembles; and on the morning of Khao Phansa, after alms and a feast for the monks, the candles were judged, prizes were given, and the winning towers were paraded through the principal streets on decorated carts and horse-drawn carriages, young women holding the candles, before a lottery decided which of the city's twenty-four temples received which candle. The first procession circled Ubon on 20 July 1901.
It is a description of an administrative achievement. The commissioner of a newly organised monthon gathers the temples of his capital, sets them in competition, routes the result past the government hall, and distributes the prizes by lot. The candles were devotional, and the delight was real. The event was also, from its first morning, an instrument of order.
The Missing Accident
Ask in Ubon today why the festival began and you will hear a different story: that the town's great festival of the eighth-month season had been Bun Bang Fai, the rocket festival, until a year when it went catastrophically wrong, a rocket falling among the crowd, the day collapsing into drunken violence, and the prince abolishing the rockets and giving the town candles instead. It is a tidy story, a public-order measure flowering into art, and versions of it appear in the tourism literature, the provincial histories and the festival's own telling.
The trouble is that the versions do not agree, and the earliest account does not contain it. In some retellings the falling rocket kills onlookers; in others there are injuries and brawling but no deaths; the provincial account has the trouble at Thung Si Mueang, others at the riverside temple of Wat Luang. Soraphot Sewanakunakon, a lecturer at Ubon Ratchathani University who has both judged the candle competition and made art about this history, tells it differently again: that the fighting was between the prince's own men and local people, and that people died in it. And Toem, the foundational source, describing the first procession in loving detail, mentions no accident at all. What every version shares is only this: the rocket festival, the great rains-calling rite of the Lao and Isan world, was banned in the monthon capital, and an orderly procession of candles to the temples took its place, under royal patronage, with the government hall at its centre.
The Ground
Between 1901 and 1902 the Isan provinces rose in the millenarian revolt remembered as the Phu Mi Bun, the Holy Men: village prophets announcing the end of the old order, thousands following them, and the Bangkok state suppressing the movement with modern arms, decisively at Ban Sapue, north of Ubon, in April 1902. In the aftermath, captured leaders were put to death. Local historians record that the executions took place at Thung Si Mueang, the open field at the centre of Ubon, and there is a story, told in the city, that the prince watched from Wang Sangat, his residence just to the north-east. It is the same field where the candles now stand floodlit every July. No marker records it. The park today holds monuments to civic virtue and a giant replica candle, and, as Soraphot observes, almost no one under a certain age in Ubon knows that anyone died there.
The sequence, precisely: the first candle procession in July 1901, as the movement was gathering; the suppression and the executions in 1902; and the procession, thereafter, an annual fixture of the monthon capital. Whether the abolition of the rockets and the institution of the candles were part of the pacification, or merely adjacent to it, is a judgement the sources do not settle. Soraphot points to what is visible: the festival's history overwritten by its own splendour, the patterns pressed into the wax descending from the central-Thai craft schools rather than from Isan design, and a rite of the Lao countryside replaced, in the years of the revolt, by a competition conducted in front of the government hall. The candle procession is many things, and one of them is the story the state told Isan about what its devotion should look like.
The Craft
None of this is why people come, and none of it diminishes what the candle-makers built, which took its own century to become what it is. The first candles were functional: real tapers bundled in tiers, made to be lit and to burn through the three months of the rains retreat, light for the monks to study by. In 1927 the makers began casting whole candles in wooden moulds. Around 1937 a craftsman named Pho Song Si, working for Wat Thung Si Mueang, invented the pressed-wax technique, moulding classical patterns in softened beeswax and applying them to the candle's body, and his successor Suan Khunphon elaborated the art with sculpted animals and fretwork bases. The state tourism organisation put its weight behind the festival from 1977, the Tourism Authority followed in 1999, and the competition became national: bigger candles, prize money, professional carvers, and, as the local historian Nikorn Wisaphen notes with some regret, a loosening of the old bond between each neighbourhood and its temple that the candle-making once renewed every year.
The old candles, Nikorn observes, were made to be lit. The modern towers, cast and carved and ten metres long, cannot be lit at all: they exist to be judged, paraded and photographed, and they tell the Buddha's story on their surface instead of burning for him in a temple hall. The offering became an image of the offering. That, in one object, is the history of the festival.
"The offering became an image of the offering."
Going
Go anyway, and go knowing. The days to travel for in 2026 are 29 and 30 July, when the processions circle Thung Si Mueang, with the communities gathering on the 28th and the candles displayed and floodlit from 13 July to 17 August. Book accommodation months ahead. Arrive a day early for the temple workshops, where the carvers finish through the night and the neighbourhood keeps them company; many visitors find the workshops more moving than the parade. Stay for the night displays, when the wax catches the light. And at some quiet moment, walk out into the middle of Thung Si Mueang itself, away from the floodlights, and stand for a minute on the grass. The candles are genuinely magnificent, the devotion around them is real, and the ground beneath them remembers more than it says. The festival is at its truest when you can hold all three at once.
