# Changi

Changi (/ˈtʃɑːŋi/) is a planning area located in the geographical region of Tanah Merah in the East Region of Singapore. Sharing borders with Pasir Ris and Tampines to the west, Changi Bay to the southeast, the South China Sea to the east and the Serangoon Harbour to the north. It is further divided into the subzones Changi Airport, Changi Point and Changi West. Changi, excluding the two water catchments and islands of Singapore, is the largest planning area by land size.
Today, Changi is an aviation hub. It is the location of both the Changi Airport and Changi Air Base. Also located within Changi is Singapore's largest prison, Changi Prison. It was used as a Japanese prisoner-of-war camp during the occupation of Singapore in World War II. The prison is Singapore's oldest operating internment facility.

## Etymology

The early Malay place name of Changi was Tanjong Rusa (English: Deer cape), as written in the 1604 Godinho de Eredia map of Singapore.
The name Changi was known in the early 19th century. In the 1828 map by Franklin and Jackson, the extreme southeastern tip of the island is referred to as Tanjong Changi. Vessels using the Johor Straits would have to pass by Changi.
There are many versions of the etymological roots of the name Changi. The first director of the Singapore Botanic Gardens Henry Ridley suggested that it gets its name from a tall tree, Pokok Chengal or Cengal (Malay for Neobalanocarpus heimii, also known as Balanscorpus heimii or Balano scorpas), which was common in the area in the early nineteenth century. It is also written and pronounced as "Chengai". Its heavy timber is commonly used for buildings and furniture and noted for its strength and deep rich colour. Other sources suggests that it comes from a climbing shrub found in the area, the changi ular (Hopea sangal), or chengal asir (Thottea piperiformis).
During the early surveys in the 1820s to 1830s of Singapore island, Changi was also named Franklin Point after Captain Franklin who was involved in these early surveys.

## History

Early Changi was mostly a malaria mosquito infested swampland and jungle that had several kampongs spread across the vast area. Several of these kampongs included from north to south, Kampong Changi, Kampong Telok Paku, Kampong Ayer Gemuroh, Kampong Somapah, Kampong Mata Ikan and Kampong Padang Terbakar, although the exact founding dates of many of these kampongs are unknown. The place was first redeveloped by the British as a summer house and a getaway location from the city centre of Singapore in the 1890s, and was prized for its tranquillity and remoteness. The existence of the resorts there today still bear testament to the original redevelopments there.
Starting from the 1920s due to increasing tension across Asia and Europe in anticipation for war, the British starting building up its military presence at the area and this included the construction of military barracks and the infamous Changi Hospital, with Chinese and Indian labourers brought in from the city. Defences along Changi's southern coast were also beefed up with the construction of machine-gun pillboxes in anticipation of the Imperial Japanese Army arrival by sea. Construction was briefly halted during the Great Depression but was subsequently resumed as these structures were considered vital for the defence of Singapore.
During World War II (WWII), the area saw mass mobilisation of Allied troops in anticipation of a Japanese invasion from the north-eastern coasts of Singapore as the Japanese had moved to capture the neighbouring Pulau Ubin from Malaysia. However it was a bluff that drew vital resources from the west of Singapore that was the eventual landing site used by the Japanese. The area also saw action of three giant artillery guns called the Johore Battery, though their usefulness in defending Singapore has been questionable.
In 1942, after the surrender of the British in Singapore, Allied Prisoners-of-Wars (POW) were made to march from the city to Changi Prison and the surrounding barracks where they were interned. The POW Camps were overcrowded and life as described by those who were interned there was unbearable, multiple incidents including the Selarang Barracks incident took place. Civilians were also not spared, the Sook Ching massacre which targeted mainly the Chinese population, took place at multiple locations in Changi, most notably at Changi Beach Park. Thousands were believed to have been executed in these areas. It was during this time too that the Japanese were also involved in the planning and construction of Changi Air Base.
After the war in 1945, the British continued to maintain Changi for military purposes, while rebuilding up the area to include accommodations, schools and resorts. They continued to do so even after the independence of Singapore in 1965, as with other areas like Seletar and Tengah. The coast along the eastern side of Changi also saw government bungalows and resorts opened for civil servants use. In 1971, because of the East of Suez policy that was announced by the British earlier in 1968, there was a sudden and large withdrawal of British troops from Changi. The vacated area saw many people whose livelihood and businesses depended on providing for the British forces becoming jobless and unsustainable. However, there were still contingents of ANZUK troops that were left in its place and the government of New Zealand even bolstered its presence in Singapore in the wake of the British withdrawal to maintain its interest in the region. The area then later became home to several of Singapore Armed Forces units too.
Changi was then revitalised with Changi Village and Somapah spruced up and Changi Airport being constructed in the area after land reclamation took place. However, this caused further disruptions to the livelihood of the residents as they had to make way for the airport and later the many other redevelopments in the area including high tech industrial estates. Finally in 1989, the last of New Zealand troops withdrew and all its remaining assets were handed over to the Singapore government. Redevelopment works continued into the 21st century with the progressive opening of the airport's terminal 3, 4 in 2008 and 2017, and the new Changi Prison Complex in 2004. Despite the strong progress of these developments, there were several ventures that were eventually stalled, like the Changi Motorsports Hub, which was expected to open as Singapore's first permanent motor racing circuit, but was halted in 2013.
Future development of Changi is in the pipelines with a mega-sized Terminal 5 and the Changi East Industrial Zone expected to be ready before 2030.

## Geography

The terrain in Changi is generally flat because most of Changi today sits on reclaimed land, there are however three notable hills in the Changi Village area, Battery (Biggin) Hill, Fairy Point Hill and Temple Hill. The ground conditions on reclaimed land however were soft marine clay which could not support the runway and taxiways of the airport, and thus works had to carried out accordingly to drain the water and strengthen them. There are also two reservoirs located in Changi, the Changi Creek Reservoir and South End Reservoir which are located to the north and south of Changi Airport respectively. The Changi planning area as defined by the Urban Redevelopment Authority encompasses the subzone of Changi Airport, Changi Point and Changi West, although in comparison to the parliamentary electoral boundaries or the Changi Estate that is commonly known in public they all differ from one another slightly.

## Amenities

There are numerous amenities spread around Changi. They include shopping malls like Changi City Point and even Changi Airport, which is considered to be a shoppers' paradise with duty-free shopping available inside the airport's transit area. Besides those, the Changi Village hawker centre is renowned for its food options, with shophouses also found around the area for the convenience of its residents. Food and amenity centres are also found all around the industrial estates, including the airfreight centre.
Places of worship in the area include Changi Bethany Church, Maranatha Bible Presbyterian Church, Sree Ramar Hindu Temple and Yan Kit Village Chinese Temple.

### Education

Currently the Singapore University of Technology and Design (SUTD), Singapore's fourth autonomous university, is located at its permanent campus in Changi. Otherwise there are presently no public government schools in Changi but there were several that used to operate in its history. Additionally there are also several private and international schools operating in the area like BNP Paribus Campus, One World International School and Singapore Aviation Academy.
These were the schools that used to operate from Changi and most were cleared away for the construction of Changi Airport. All but one of them are now defunct, namely:

* Ting Ying Chinese School, from 1933 to c.1973, the site is now occupied by runway 02L/20R of Changi Airport
Additionally the British and later the Australian and New Zealand (ANZ) government opened schools for children of servicemen deployed in Singapore:
* British Army's Children School (Selarang), from c.1950 to 1971, later converted to ANZ Primary School Selarang, which lasted from 1971 to 1973, the site was near Selarang Camp
* Changi Junior and Infant School, until 1971, the site is now occupied by the north portion of Changi Air Base West
* RAF Changi Grammar School, from 1963 to 1971, later converted to ANZ High School Changi, which lasted from 1971 to 1973, the site at 1800 Upper Changi Road North is now state property

### Other industries

Changi Business Park and Changi North Industrial Park are industrial estates located within Changi that have aeroplane related businesses housed in them, like Collins Aerospace, but the industrial parks also contain many other businesses that are unrelated to the operations of Changi Airport. The businesses there may range from logistical, to electronics and even banking. There is also the Singapore Expo which provides companies with a place to hold conventions and exhibitions.

## Security

Changi, except for its airport, falls under the jurisdiction of the Bedok Police Division, and the Loyang Fire Post that is supplemented by the 2nd Singapore Civil Defence Force DIV HQ. Immigration and custom controls at all ferry terminals are controlled by ICA.

### Airport

The Airport Police Division is responsible for the overall security of Changi Airport. It is supported by auxiliary police like AETOS, Certis CISCO and SATS Security, that are usually deployed as front line officers for baggage and personnel screening as well as controlling entry points into transit areas, including the airfreight centre. The airport police is further supported by the Police K9 Changi Base and the 9 SIR infantry soldiers to maintain protection of the airport. ICA works independently from the airport police and maintains control over immigration and customs in all terminals and air cargo entry points. It works with the Singapore Customs in customs and excise related issues. The airport has its own firefighting and rescue services, the Airport Emergency Service (AES) that operates two fire stations and one fire substation that are located around the airport's runway. It also has two casualty clearance stations and one sea rescue base located at Changi Airport Fuel Hydrant Installation (CAFHI) Jetty. AES operates 18 firefighting vehicles, two hovercraft and two fire boats.

#### Train

Changi is served by 3 MRT stations, Changi Airport on the East West MRT line, Upper Changi on the Downtown MRT line and Expo which is an interchange station for both lines. All of the stations are located in the south or central of Changi, hence there are no MRT stations in the vicinity of Changi Village or the airfreight centre, located in the north. Xilin MRT station is under construction as part of the Downtown line extension and would bring greater connectivity to Changi Business Park when it opens in 2026. There are however plans for the northern part of Changi as well as the upcoming Changi Airport Terminal 5 to be linked via the Cross Island MRT line and Thomson–East Coast MRT line.
Changi Airport is served internally by the Changi Airport Skytrain system that operates between Terminals 1, 2 and 3, both in the transit as well as public areas.
