# Chiang Rai

Chiang Rai (Thai: เชียงราย, pronounced; Northern Thai: ᨩ᩠ᨿᨦᩁᩣ᩠ᨿ, เจียงฮาย, Northern Thai pronunciation:) is the northernmost major city in Thailand, with a population of about 200,000 people. It is located in Mueang Chiang Rai District, Chiang Rai Province. Chiang Rai was established as a capital city in the reign of King Mangrai, in 1262 CE.

## History

The city was founded by King Mangrai in 1262$^{:208}$ and became the capital of the Mangrai Dynasty. The word 'Chiang' means 'city' in Thai, so Chiang Rai would mean 'the City of (Mang) Rai'. Subsequently, Chiang Rai was conquered by Burma and remained under Burmese rule for several hundred years. It was not until 1786 that Chiang Rai became a Siam vassal. Siam (later Thailand) annexed the Kingdom of Chiang Mai in 1893 as a Monthon, which Chiang Rai joined later in 1910. It's not before 1933 that Chiang Rai became a full province of Thailand.
In 1432, during the reign of King Sam Fang Kaen of the Mangrai Dynasty (1402–1441), the Phra Kaeo, or Emerald Buddha, the most revered Buddha statue, was discovered in Chiang Rai when an earthquake split the chedi at Wat Phra Kaeo of Chiang Rai city. The jade figure was then seen concealed within. Another telling of the story has the "Emerald Buddha" hastily covered in mud just before marauders entered to pillage. Many years later, the clunky-looking mud Buddha was found to actually house a magnificent jade statue, perhaps by way of the earthquake mentioned above—which caused a piece of the clay to break off—revealing the jade beneath.
In 1992, the city pillar was moved from Wat Klang Wiang to Wat Phra That Doi Chom Thong, where it is known as Sadue Mueang (Thai: สะดือเมือง), the "navel" or omphalos of the city.

## Geography

Chiang Rai lies on the flat alluvial plain of the Kok River, a tributary of the Mekong, between the Daen Lao Range in the north and the Phi Pan Nam Range in the south. The Kok River runs along Chiang Rai's north side, flowing eastwards out of Burma at Tha Ton(ท่าตอม) town, bending north-eastwards and joining the Mekong River about 40 kilometres (25 mi) north-east of the city. The Lao River, a tributary of the Kok, flows south of Chiang Rai.
There are four bridges spanning the Kok River within the town's boundaries, each running south–north. Most of the terrain surrounding Chiang Rai town is either flat or has moderate hills. The exception is outward in the west and north-west directions, where limestone hills are evident, some of which have vertical exposed cliffs. That is also the direction where most of the region's hill tribe people have their villages, further afield.
The city is 860 kilometres (530 mi) north of Bangkok, about 200 kilometres (120 mi) north-east of Chiang Mai, 62 kilometres (39 mi) south of Mae Sai and the Burmese border; 60 kilometres (37 mi) south-west of the town of Chiang Saen on the Mekong River across from Laos; and 90 kilometres (56 mi) north of Phayao town. The Golden Triangle, the tripoint of the Thailand, Laos and Myanmar borders, is 55 kilometres (34 mi) north-east of the city.

## Transportation

Route 1 runs from Bangkok through Chiang Rai to Mae Sai on the Burma border. Chiang Rai is 839 kilometers from Bangkok, about 14 hours by car or by bus. According to official bus schedules, the bus ride to Chiang Rai from Chiang Mai takes approximately 3 hours and 30 minutes, All of these times should take into account the rainy season which lasts from about June to late October, this can severely inhibit travel with road sections often completely flooded and even washed out.
Several flights are available to and from Bangkok daily. Chiang Rai International Airport flight time is about 1 hour and 30 minutes. There are several major operators including Thai Airways, Air Asia, Nok Air.
There is scheduled boat service between Chiang Rai and Thaton in Chiang Mai Province daily. This journey will last about 3–4 hours and is a pleasant alternative to the bus ride through the mountains.
There are currently no rail services to Chiang Rai as the railway line from Bangkok ends at Chiang Mai. Nonetheless, new 323 kilometer-long branch line, from Den Chai to the Lao border at Chiang Khong and passing through Chiang Rai, is under construction and is expected to open in 2028.
