Kallang Airport was the first purpose-built civil international airport in Singapore, opened officially on 12 June 1937 and ceased operations in 1955, when it was relocated to Paya Lebar. Situated on the eastern shore of the Kallang Basin, the Kallang Airport spanned the modern planning areas of Kallang and Geylang at its greatest extent. The conserved complex, including the airport's terminal building, is located wholly within Kallang.
