Map of Thailand highlighting Kanchanaburi province
Kanchanaburi (กาญจนบุรี,pronounced[kāːn.t͡ɕā.ná(ʔ).bū.rīː]) is the largest of the westernprovinces (changwat) ofThailand. Tourists are attracted by the history of its ancient civilization and the World War II Bridge over theRiver Kwai, originally spelt "Khwae" but officially changed to Kwai to accommodate the expectations of tourists.
Archaeological remains found in Kanchanaburi date back to the 4th century, with evidence of trade with surrounding regions at that time. Very little is known about the historicalKhmer influence in Kanchanaburi, butPrasat Muang Sing, one of the country's most well-known Khmer sites, provides evidence of their occupation.
Not much was historically recorded about Kanchanaburi province before the reign of KingRama I, but some historians believe that the province was of strategic importance during the Ayutthaya period, since it was on the invasion route from Burma.[5] In 1982, many human and elephant skeletons and swords were found inPhanom Thuan district, leading to speculation that this site might even have been the site of the famous battle ofKing Naresuan against the Burmese crown prince, most commonly assigned to theDon Chedi district in nearbySuphanburi province.
Most foreigners are mainly aware of Kanchanaburi's recent history with theBurma Railway. During theJapanese occupation of Thailand in 1942, both allied POWs and Asian labourers were ordered by the Japanese to build a Thailand-Burma railway. Eventually, more than 100,000 people (16,000 allied POWs and 90,000 local Asian labourers) died from horrific working conditions.[6]
The province is in the west of Thailand, 129 km from Bangkok, and covers a total area of approximately 19,482 km2 (7,522 sq mi). It is the country's third largest province, after Nakhon Ratchasima and Chiang Mai. Topographically, it is covered with timber and evergreen forests. The total forest area is 11,990 km2 (4,630 sq mi) or 61.5 percent of provincial area.[1] The district covers the source valleys of the rivers Kwae Yai andKwae Noi ("River Kwai"), which merge atKanchanaburi city to form theMae Klong River. The neighboring provinces are (clockwise, from the north)Tak,Uthai Thani,Suphan Buri,Nakhon Pathom, andRatchaburi. In the west it bordersKayin State,Mon State, and theTanintharyi Region ofMyanmar. Bong Ti is a transnational border crossing point, which is expected to gain in importance if the plannedDaweideepwater port project goes ahead, along with a highway and a railway line betweenBangkok and the port.[7]
Kanchanaburi province has atropical savanna climate (Köppen climate classificationAw). Winters are dry and very warm. Temperatures rise until April, which is very hot with the average daily maximum at 37.8 °C (100.0 °F). Themonsoon season runs from May through October, with heavy rain and somewhat cooler temparatures during the day, although nights remain warm.
