Leung Shuen Wan was connected to the mainland in the 1970s to form the High Island Reservoir. It had historically an area of 8.511 km² and was in 1960 the 4th largest island of Hong Kong. At that time, the airport platform had not yet been built and the area of Tsing Yi increased later as a consequence of land reclamation.

The original Chek Lap Kok had an area of area of 3.02 km² (other sources mention 2.8 km²).
