Wat Phra That Doi Kham a hill of kept promises

Published accounts of the rite add two details our photograph does not show: you begin by lighting three sticks of incense, and you ask for one thing at a time.^1,3

If you are not making a vow, watch from the side, keep your voice down and do not walk in front of people sitting before the shrine.

The legend of the hill

Tradition places the founding in the reign of Queen Chamadevi of Hariphunchai, the kingdom of the Mon people centred on present-day Lamphun, south of Chiang Mai. Her two sons, Mahantayot and Anantayot, are said to have built a chedi here (the bell-shaped relic monument of northern Thai temples) to enclose an older reliquary.^2,5 No archaeological dating has been published that we know of, and no historian has confirmed the date of 687.

The name has a legend of its own, set even earlier. The Buddha is said to have come to this hill, converted a yakkha couple (giants of Buddhist legend), Pu Sae and Ya Sae, and given them some of his hair. Heavy rain then washed gold into a cave on the hill: doi means mountain, and kham gold.^2,5

The chedi and its relics

A plaque by the chedi's stair, whose balustrades take the form of nagas (mythical serpents), names hair relics, kesa-dhātu, in a verse of homage in Pali, the language of early Buddhist texts. A second plaque addresses relics of the Buddha and of his enlightened disciples.

The chedi you see today dates from after 1966. That year, with the temple abandoned, its relic chamber was found open; among the objects recovered from it, and kept by the temple, were a large gilded sandstone Buddha, Phra Rot Luang (not the big Buddha on the summit), and clay votive tablets.^2,6 Accounts differ on the cause: some blame rain and a collapse, a Thai blog blames looters.^6,7 According to the temple's history plaque, the sheathing of the chedi was part of the restoration that began in 1981.^6,8

Once a year, on the seventh and eighth days of the waning moon after Visakha Bucha (the full moon that marks the Buddha's birth, enlightenment and death), the relics are ritually bathed. The date follows the lunar calendar and falls in late May or June.⁹

Work on the 1994 hall goes on. Next to its door, a donation box reads 'gilding, burying the luk nimit': the stone balls buried around an ordination hall to mark its sacred boundary. At the foot of the stair, ropes hang from a bar under a small sign, 'ball no. 2, east, in homage to Aññā Koṇḍañña', the Buddha's first disciple. The hall may be, or may be about to become, an ordination hall; we could not confirm it, nor find out when the balls will be buried.

Pu Sae and Ya Sae, the yakkha of the legend, are still honoured as guardian spirits of Chiang Mai. The temple has altars to them, and another stands by the road up the hill.^6,15 Every year in late May or June, an offering ceremony is held for them at the foot of the hill, not at the temple; in 2026 the Mae Hia municipality held it on 30 May at a Doi Suthep-Pui National Park station.^15,16 The rite blends older beliefs of the Lua, a people settled in the region before the northern Thai, with Buddhist practice: a procession behind a painted cloth of the Buddha, prayers, a medium and the offering of a buffalo.^16,17

On the back terrace lies a reclining Buddha with a white face and a gilded robe. At its foot, two plaques carry prayers to Guanyin, the Chinese bodhisattva of compassion, and to Ganesh, the elephant-headed Hindu god of beginnings. Elsewhere on the summit, gilded yakkha guardians each hold a club.

The doorway of the 1994 hall is worth a stop: two painted scenes from the Buddha's life, a gilded peacock on an arch of mosaic, and carved doors.

The view alone is worth the climb. A gate on the edge of the summit, signed 'Doikham Panorama View Point', opens onto the plain: Chiang Mai's towers to the east and, by several accounts, the airport.^11,18 Two gilded figures carrying baskets, a large teddy bear in glasses and a few rabbit figurines keep it company.

The hill lies west-south-west of the city, so the view faces east, with the late-afternoon light behind you. The sun sets behind the hill and the temple closes at 18:00: this is not a sunset spot.
