Chon Buri History & Heritage Guide 2025
Journey through the fascinating history and heritage sites of Chon Buri.
Chon Buri is a coastal province on Thailand's Eastern Seaboard, best known for the resort city of Pattaya and its string of sun-drenched beaches along the Gulf of Thailand. The province blends vibrant beach tourism with industrial heritage, traditional fishing villages, and lush tropical landscapes just 80 km from Bangkok.
Chon Buri has been inhabited since prehistoric times, with evidence of Bronze Age settlements along the Gulf coast. The area was part of the Khmer Empire's eastern reaches before coming under Siamese control in the 13th century, becoming an important port and fishing province. In the 19th century King Chulalongkorn (Rama V) chose Ko Si Chang island as his summer residence, cementing Chon Buri's royal connection. The 20th century saw the transformation of the sleepy fishing village of Pattaya into one of Asia's most famous beach resort destinations, accelerated by American military leave programs during the Vietnam War era.
Historical Timeline
Key moments in Chon Buri's history.
Early Gulf Coast Settlements
Archaeological evidence confirms Bronze Age settlements along the Chon Buri coastline, with inhabitants relying on fishing and coastal trade along the Gulf of Thailand.
Khmer Influence
The region fell within the sphere of the Khmer Empire, which dominated much of mainland Southeast Asia. Remnants of Khmer-period religious sites exist in the eastern hinterland.
Siamese Kingdom Integration
As the Khmer Empire declined, Chon Buri was absorbed into the Sukhothai and later Ayutthaya kingdoms, becoming an important coastal province and fishing hub for the Gulf of Thailand.
Ayutthaya Era Trade
Chon Buri's ports participated in the flourishing Gulf of Thailand trade network during the Ayutthaya Kingdom's golden age, trading dried fish, shrimp paste and tropical produce.
Rama V and Ko Si Chang
King Chulalongkorn (Rama V) developed Ko Si Chang island as a royal retreat, constructing the Chudhadhut Palace and a number of royal structures. The French briefly occupied the island in 1893 during the Franco-Siamese crisis.
French Occupation of Ko Si Chang
During the Franco-Siamese War, French forces occupied Ko Si Chang and used it as a base. The treaty that followed forced Siam to cede territories east of the Mekong River, a defining moment in Thai national memory.
Bang Saen Beach Development
Prime Minister Plaek Phibunsongkhram officially developed Bang Saen Beach as Thailand's first organized public beach resort, establishing facilities that made it the country's most popular domestic beach destination.
Pattaya and the Vietnam War
American military personnel from U-Tapao Air Base and US forces in Vietnam began using the small fishing village of Pattaya for rest and recreation, triggering rapid development of hotels and entertainment that would define the city's character.
Pattaya Becomes a City
Pattaya was officially designated a city under a special administrative law, reflecting its explosive growth from village to major tourist destination in just two decades.
Sanctuary of Truth Construction Begins
Millionaire Lek Viriyaphant begins construction of the Sanctuary of Truth (Prasat Sajja Tham), an all-wood temple complex that continues to be built and carved to the present day.
Eastern Seaboard Industrial Development
Laem Chabang in Chon Buri was developed into one of Southeast Asia's busiest container ports, transforming the province's economy with major industrial investment alongside continued beach tourism growth.
