Si Racha[2] (Thai: ศรีราชา, pronounced [sǐː rāːt͡ɕʰāː]) is a subdistrict and town in Thailand on the east coast of the Gulf of Thailand, about 120 km (75 mi) southeast of Bangkok in Si Racha district, Chonburi province.

Key Information

The town is the center of the Si Racha district, the ninth-largest urban city area in Thailand. Si Racha is in the industrial Eastern Seaboard zone, along with Pattaya, Laem Chabang, and Chonburi. It is also part of the Pattaya-Chonburi Metropolitan Area, a conurbation with a population of 999,092 people.

Si Racha is known as the birthplace of the popular hot sauce, Sriracha, which is named after the town.[3]

History

[edit]

Si Racha used to be part of Bang Lamung district which it borders today to its south. In 1900 (B.E 2443) Field Marshal Chao Phraya Surasak Montri came to the area of the modern town and built a sawmill under his company Sriracha Capital Company Limited. In 1903, Surasak Montri requested that the district capital of Bang Phra district be moved to Si Racha, which it did but retained its original name before becoming Si Racha district in 1917.[4]

The municipality was created as a subdistrict municipality (thesaban tambon) in 1945.[5] In 1995, the subdistrict municipality was upgraded to a town municipality (thesaban mueang).[6]

On 3 September 2023, an oil pipeline being used to fill an oil tanker off a jetty owned by Thai Oil ruptured, causing an oil spill. The spill polluted the Gulf of Thailand with 50-70 m³, producing a 5 km slick. The spill is currently under the authority of the Pollution Control Department and the Marine Department. Thai Oil was later given permission to use 6,000 litres of dispersant on the slick.[7] As of 7 September 2023, the coral off the coast of islands in the gulf have been unaffected by the spill.[8]

Unrelated to the oil spill, on 8 September the waters off Si Racha experienced a plankton bloom caused by recent monsoons that had occurred across the country, causing the beaches up to Bang Saen Beach to be covered by dead marine life, including ponyfishes, crabs, pufferfishes, and tilapias.[9][10]

Education

[edit]

The Thai-Japanese Association School Sriracha, a Japanese international school, is in Si Racha. It is an affiliate of the Thai-Japanese Association School in Bangkok.[11] Si Racha formerly housed the Sriracha-Pattaya Japanese Supplement School, a Japanese weekend school.[12]

History

Pre-20th Century Origins

Si Racha's early history is rooted in the broader pre-colonial dynamics of eastern , where the region encompassing modern experienced influences from Mon and Khmer migrations dating back to the period (6th–11th centuries CE) and the subsequent expansion. Archaeological evidence indicates that eastern served as an interface zone between Mon-Dvaravati polities to the west and Khmer kingdoms to the east, with cultural exchanges evident in artifacts and settlement patterns along the coastal areas. By the Ayutthaya period (14th–18th centuries), the locale had developed into a small , sustained by its coastal position and reliance on marine resources such as and , which supported subsistence economies for local communities. This settlement was originally integrated into the larger , functioning as a peripheral coastal outpost without distinct administrative status, and its economy centered on traditional practices with wooden piers that persist in remnants today. The village's minor port role facilitated limited local exchange, including salt production and , reflecting the region's enduring ties to Khmer-influenced maritime networks in eastern . The transition toward formalized development began in 1900, when Chao Phraya Surasak Montri, a prominent nobleman and former Minister of Agriculture, established the Sri Maha Racha in the area under his Capital Company Limited, introducing initial economic diversification beyond . This venture marked the village's shift from a subsistence fishing community to an emerging hub, laying groundwork for its separation from shortly thereafter.

20th Century Development and Modern Events

In the early , Si Racha underwent significant administrative transformations that laid the foundation for its modern governance. This shift was followed by the elevation of Si Racha to full district status in 1917, separating it from neighboring areas and formalizing its administrative boundaries within . Further milestones included its designation as a subdistrict municipality (thesaban tambon) in 1945, reflecting post-World War II urbanization efforts, and its upgrade to town municipality (thesaban mueang) status in 1995, which expanded local governance capabilities to manage growing urban demands. The mid-to-late marked Si Racha's emergence as an industrial powerhouse, driven by its integration into Thailand's Eastern Seaboard Development Programme (ESDP) launched in the early . This initiative, part of the Fifth National Economic and Social Development Plan (–), focused on like deep-sea ports, railways, and industrial estates to boost export-oriented manufacturing in and adjacent provinces. Si Racha benefited directly through projects such as the Si Racha-Laem Chabang Railway branch line. These developments transformed the area from a and trading outpost into a key hub for , automotive assembly, and shipping, attracting foreign investment and fostering economic diversification. Si Racha's population has expanded considerably since the post-World War II era, fueled by internal migration drawn to emerging industrial opportunities. Thailand's overall population surged from about 19 million in 1950 to over 60 million by 2000, with significant rural-to-urban shifts supporting factory labor in eastern provinces like Chonburi. In Si Racha, this influx contributed to a district population of 323,797 as of 2019, alongside a large transient workforce in industrial zones. Recent events underscore ongoing challenges, including environmental risks from industrial activities; on September 3, 2023, a pipeline rupture at Thai Oil's jetty leaked 50–70 cubic meters of crude oil into the Gulf of Thailand, forming a 5-kilometer oil slick and raising concerns over potential damage to nearby coral reefs and marine ecosystems. Cleanup efforts contained the spill within days, but monitoring continues to assess long-term ecological impacts. A similar incident occurred on June 5, 2025, when approximately 20 tons of crude oil leaked from Thai Oil's buoy system near Ko Sichang, creating surface slicks due to weather conditions; the spill was contained by June 7, 2025, with no visible oil remaining and ongoing assessments for environmental effects.
