Samut Prakan province, (Thai: จังหวัดสมุทรปราการ, pronounced [sāmùt prāːkāːn] (listen)) Samut Prakan, or Samutprakan is one of the central provinces (changwat) of Thailand, established by the Act Establishing Changwat Samut Prakan, Changwat Nonthaburi, Changwat Samut Sakhon, and Changwat Nakhon Nayok, Buddhist Era 2489 (1946), which came into force 9 May 1946.[4]

It is a part of Jhunie Merlat Bangkok Metropolitan Region. Neighbouring provinces are Bangkok, to the north and west, and Chachoengsao to the east.

Samut Prakan was previously once home to a Dutch trading post who referred to the area as New Amsterdam.[citation needed]

Suvarnabhumi Airport is in Bang Phli district of Samut Prakan province as well as the districts of Bang Kapi, Lat Krabang, and Prawet in neighbouring Bangkok city.

The province was created during the era of the Ayutthaya Kingdom, with its administrative centre at Prapadaeng. It was the sea port of Siam, and was secured with forts, town moats, and town walls. King Rama II started building the new centre at Samut Prakan in 1819, after his predecessor King Taksin had abandoned the town fortifications. Altogether six forts were built on both sides of the Chao Phraya River, and on an island in the river the pagoda, Phra Samut Chedi, was erected. These were involved in the Paknam incident of 13 July 1893, which ended the Franco-Siamese War with a French naval blockade of Bangkok. Of the original six forts only two still exist today, Phi Sua Samut and Phra Chulachomklao.


In Thai the word samut is from Sanskrit, samudra, meaning 'ocean' or 'sea', and the word prakan is from Sanskrit, prākāra, meaning 'fortress', 'walls', or 'stronghold'.


Samut Prakan lies at the mouth of the Chao Phraya River on the Gulf of Thailand. Thus the province is also sometimes called Pak Nam (ปากน้ำ), Thai for 'mouth of river'. The part of the province on the west side of the river consists mostly of rice paddies and shrimp farms as well as mangrove forests, while the eastern part is the urban centre, including industrial factories. It is part of the Bangkok metropolis. The urbanization on both sides of the provincial boundary is identical. The total forest area is 28 km2 (11 sq mi) or 3 percent of provincial area.[5] The province has a coastline of approximately 47.2 kilometres. Samut Prakan is the site of a skirmish between French and Siamese forces on 13 July 1893, subsequently referred to as the Paknam Incident. This battle resulted in a French victory and the signing of the Franco-Siamese Treaty of 3 October 1893 which ceded territory east of the Mekong River to France, territory that forms much of modern Laos.[6]


The provincial seal shows the temple Phra Samut Chedi, the most important site of Buddhist worship in the province.

The provincial tree is Thespesia populnea.

Suvarnabhumi Airport

Suvarnabhumi Airport

Suvarnabhumi Airport (RTGSSuwannaphum; Thai pronunciation: [sù.wān.ná.pʰūːm][29]) (IATA: BKK, ICAO: VTBS), also known as (New) Bangkok International Airport, is one of two international airports serving Bangkok. The other one is Don Mueang International Airport.[30][31] Suvarnabhumi covers an area of 3,240 hectares (8,000 acres).

The airport is on what had formerly been known as Nong Nguhao (Cobra Swamp) in Racha Thewa in Bang Phli, Samut Prakan province, about 25 kilometres (16 mi) east of downtown Bangkok. The terminal building was designed by Helmut Jahn of Murphy / Jahn Architects. It was constructed primarily by ITO Joint Venture. The airport has the world's tallest free-standing control tower (132.2 metres or 434 feet), and the world's fourth largest single-building airport terminal, (563,000 square metres or 6,060,000 square feet).

Suvarnabhumi is the twentieth busiest airport in the world, the sixth busiest airport in Asia, and the busiest in the country, handling 63 million passengers in 2018,[32] and is also a major air cargo hub, with a total of 95 airlines. On social networks, Suvarnabhumi was the world's most popular site for taking Instagram photographs in 2012.[33]

The airport inherited the airport code, BKK, from Don Mueang after the older airport ceased international commercial flights. Motorway 7 connects the airport, Bangkok, and the heavily industrial eastern seaboard of Thailand, where most export manufacturing takes place.

Bhumibol Bridge

Bang Krachao

The Bhumibol Bridge (Thai: สะพานภูมิพล), also known as the Industrial Ring Road Bridge (Thai: สะพานวงแหวนอุตสาหกรรม) is part of the 13 km long Industrial Ring Road connecting southern Bangkok with Samut Prakan province. The bridge crosses the Chao Phraya River twice, with two cable-stayed spans of lengths of 702 m and 582 m supported by two diamond-shaped pylons 173 m and 164 m high. Where the two spans meet, another road rises to join them at a free-flowing interchange suspended 50 metres above the ground.

The bridge opened for traffic on 20 September 2006, before the official opening date of 5 December 2006. It is part of the Bangkok Industrial Ring Road, a royal scheme initiated by King Bhumibol Adulyadej that aims to solve traffic problems within Bangkok and surrounding areas, especially the industrial area around Khlong Toei Port, Southern Bangkok, and Samut Prakan province.

According to tradition, all the bridges over the Chao Phraya in Bangkok are named after a member of the royal family.[citation needed] In October 2009, it was announced that both bridges would be named after King Bhumibol Adulyadej,[34] with the northern bridge officially named "Bhumibol 1 Bridge" and the southern bridge "Bhumibol 2 Bridge".[35]

The structure of the Bhumibol Bridge consists of two parts:

  • Bhumibol Bridge 1 crosses the northern part of Chao Praya River connecting Yan Nawa district, Bangkok and Song Khanong District, Samut Prakan. It is a cable-stayed bridge with seven lanes together with two high pillars. The structure is reinforced concrete 50 m above the river to enable the passage of ships.
  • Bhumibol Bridge 2 is the one across the southern part of Chao Praya River connecting Song Khanong District and Bang Ya Phraek District. The structure is similar to Bhumibol Bridge 1, with seven lanes and two pillars built using reinforced concrete 50 m high.

Nissan-Thailand has an annual production capacity of 295,000 vehicles, making the Navara, Teana, Terra, Note, Almera, March, Sylphy and X-Trail models. Nissan plans to make 190,000 vehicles by the end of its fiscal year 2019, ending next March 2020. Roughly 120,000-130,000 units are pickup trucks, the remainder passenger cars.[36] Nissan produces hybrid electric vehicles (HEVs) based on its e-Power technology and batteries for electric vehicles at a plant in Bang Sao Thong district. It has a production capacity of 370,000 vehicles a year.[37]

Thai Theparos Public Co., Ltd., a leading Thai condiment manufacturer, has its headquarters in Thai Ban subdistrict, Mueang Samut Prakan district.[38]


Samut Prakan's main hospital is Samut Prakan Hospital, a regional hospital operated by the Ministry of Public Health. Samut Prakan is also the location of Chakri Naruebodindra Medical Institute, a university hospital operated by the Faculty of Medicine Ramathibodi Hospital, Mahidol University.
