Kallang Airport, also known as Kallang Aerodrome, Kallang Airfield and RAF Kallang, opened in 1937 as Singapore's first purpose-built civil airport and was built together with an anchorage area for seaplanes along the airport's perimeter on the waterfront (on the Kallang River).
 Large tracts of land were reclaimed in the Kallang Basin to turn the vast swampy area into a circular-shaped airfield and to build a slipway for seaplanes.
 The airport was closed down in 1955 when the new Singapore International Airport at Paya Lebar (also known as Paya Lebar Airport and now operated as Paya Lebar Air Base by the RSAF) was built and opened in that same year.
 Although most of Kallang Airport was demolished soon after it was shut down and the cleared areas of the former airport were redeveloped (such as the old seaplane anchorage area and the runway), the distinctive airport terminal building, some nearby airport structures (major ones include a few of the original aircraft hangars and former airport administration blocks, some of which have been quite recently demolished) and the iconic control tower were retained and served as the headquarters of the People's Association (a major government-run community organisation in Singapore) until April 2009.
 Just a year before, the Urban Redevelopment Authority (URA) of Singapore gazetted what remained of Kallang Airport for conservation as a historic monument/landmark in the country.
 It is currently unoccupied.
