Kallang Airport

Kallang Airport (also known as the Kallang Aerodrome, Kallang Airfield and RAF Kallang) was Singapore's first purpose-built civil international airport. Officially opened on 12 June 1937 and closed on 21 August 1955, it was located along the eastern edge of the Kallang Basin and spanned the modern planning areas of Kallang and Geylang. Constructed on 300 acres (120 ha) of reclaimed mangrove swampland, the airport featured facilities for seaplanes and was once regarded as "the finest airport in the British Empire", with Amelia Earhart calling it "an aviation miracle of the East". Though its official opening was in 1937, the first aircraft landed in 1935.

During World War II, Kallang Airport was the only operational airfield in Singapore supporting the Allied forces against the Japanese. Under the Japanese occupation of Singapore, its grass airstrip was upgraded to a 5,500 feet (1,700 m) concrete runway. By 1950, growing air traffic made the airport inadequate despite expansions, prompting plans to replace it with a new facility at Paya Lebar, which opened in 1955. After its closure, parts of the airport were demolished, though key structures like the terminal building, control tower, aircraft hangars and administrative blocks were preserved and gazetted for conservation by the Urban Redevelopment Authority (URA) in 2008. The People's Association (PA) had used the site as its headquarters from 1960 to 2009.

Other parts of the former airport were repurposed. The old runway area first became Kallang Park as part of "Project Lung", then hosted the old National Stadium, and today forms the Singapore Sports Hub, including the current National Stadium and Singapore Indoor Stadium. The eastern portion became the "Old Kallang Airport Estate", one of Singapore's earliest modern residential precincts. The terminal building was also used during the 2011 Singapore Biennale. Roads such as Old Airport Road, Kallang Airport Drive and Kallang Airport Way reflect the area's aviation legacy, while Dakota Crescent, Dakota Close and Dakota MRT station commemorate the Douglas DC-3 "Dakota" aircraft and a 1946 aviation disaster. There are ongoing plans to transform the wider Kallang Airport area into a commercial and lifestyle hub.
