It may not look much like an airport, but that was exactly what the People's Association headquarters used to be. After its official opening in 1937 as Singapore's first civil airport, the then Kallang Airport operated daily flights to Kuala Lumpur, Ipoh and Penang. Air operations ceased in 1955 with the inception of Paya Lebar Airport. Designed by Chief Architect of the Public Works Department Frank Dorrington Ward, the historical landmark is well preserved, with its observation tower overlooking Nicoll Highway. Today, its grounds are taken over by the National Stadium, Kallang Theatre, the People's Association and other sporting facilities.
