Ubon Ratchathani (Thai: อุบลราชธานี, pronounced [ʔubon râːt.tɕʰa.tʰaːniː]) is one of the four major cities of Isan (with Khorat/Nakhon Ratchasima, Udon Thani, and Khon Kaen), also known as the "big four of Isan." The city is on the Mun River in the southeast of the Isan region of Thailand, and is located 615 km (382 mi) away from Bangkok. It is known as Ubon (อุบลฯ) for short. The name means "royal lotus city". Ubon is the administrative center of Ubon Ratchathani Province.
As of 2006, the Ubon Ratchathani urban area had a population of about 200,000. This included 85,000 in Thetsaban Nakhon Ubon Ratchathani (Ubon municipality), 30,000 each in Thetsaban Mueang Warin Chamrap (Warin municipality) and Thetsaban Tambon Kham Yai, 24,000 in Thetsaban Tambon Saen Suk, 10,000 each in Thetsaban Tambon Pathum and Tambon Kham Nam Saep, and 6,000 in Thetsaban Tambon Ubon.
The city was founded in the late 18th century by Thao Kham Phong, descendant of Phra Wo and Phra Ta, who escaped from King Siribunsan of Vientiane into the Siam Kingdom during the reign of King Taksin the Great. Later, Thao Kham Phong was appointed to be "Phra Pathum Wongsa" (Thai: พระประทุมวงศา)[clarification needed] and the first ruler of Ubon Ratchathani. In 1792, Ubon Ratchathani became a province and was also the administrative center of the monthon Isan. Until 1972, Ubon Ratchathani was the largest province of Thailand by area. Yasothon Province was split off from Ubon Ratchathani Province in 1972, followed by Amnat Charoen Province in 1993. Ubon Ratchathani Province now ranks fifth in area.
The city was attacked by French forces during the 1940 Franco-Thai War.
Ubon grew extensively during World War II when Japanese forces brought in prisoners of war by rail from Kanchanaburi, the survivors of the Burma Railway. One legacy of this is a monument in the city's central Thung Si Meuang Park, erected[when?] by British prisoners of war in gratitude to the citizens of Ubon Ratchathani for assisting them. During the Vietnam War, United States armed forces constructed Ubon Royal Thai Air Force Base, which is now also a dual-use commercial airport.
Some of the city's religious buildings show the influence of Lao architecture.
The elevation is 410 ft (125 m). It is 615 km (382 mi) from Bangkok.
Ubon Ratchathani has a tropical wet and dry climate (Köppen climate classification Aw). Winters are dry and very warm. Temperatures rise until April with an average daily maximum of 36.4 °C (97.5 °F). The monsoon season runs from late April to October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm.

Ubon Ratchathani is best known for its annual Candle Festival, held in July to mark the beginning of the rainy season retreat for Buddhists, Wan Khao Phansa, also called Buddhist Lent. One day prior, candles are taken to Thung Si Mueang, the central park in the middle of the city; the park is decorated and exhibited in the evening. On the same evening, there are many smaller processions during which candles are carried to practically all Buddhist temples in Thailand. The main procession in Ubon Ratchathani takes place early the next morning. The events are marked by ceremonies and processions in the form of large-scale, colourful parades of magnificent floats with huge, extravagant candlewax sculptures, Thai traditional dance and music.
Sights and attractions
The province is known for its strong Buddhist tradition, particularly the practice of monks dwelling in the forest (Thai: พระธุดงค์ Phra thudong, pilgrimage, lit. "hiking monk"). Wat Nong Pah Pong, for example, is a Buddhist forest monastery in the Thai Forest Tradition, which was established by Venerable Ajahn Chah Subhaddo in 1954. Ajahn Chah's style of teaching and personality had a notable ability to reach people of other nationalities. Many foreigners came to learn from, train under, and be ordained by Ajahn Chah. Wat Pa Nanachat (International Forest Monastery) was established in 1975. It currently has over fifty monks representing twenty-three nationalities.
Other Buddhist temples in and around the city include Wat Thung Si Mueang (Thai: วัดทุ่งศรีเมือง), in the center of the city, featuring an old wooden library on stilts in a small lake, and Wat Nong Bua near the Big C mall, featuring a chedi modelled on Bodh Gaya in India.
