Portsmouth Airport was built during 1931 and early 1932. It finally closed in 1971.
There was no room for it to expand because of Langstone Harbour on one side and the railway on the other.
As aircraft got bigger the grass runway was unsuitable and there was not the space to build the longer concrete runways needed.
However, the real nails in the airport’s coffin were two spectacular accidents in 1967 when separate planes skidded off the grass landing strip, one of them ending up on Eastern Road.
It was a miracle no one was killed, but it was enough to convince the authorities that the airport should close and the site be redeveloped.
Gary Manning posted three of the pictures here on the Memories of Bygone PortsmouthFacebook page, photos which show the early stages of work at the beginning of the 1930s.
It was also known as Portsmouth City Airport and, rather grandly, as PWA (Portsmouth Worldwide Airport).
It was one of the last remaining grass runway airports in the United Kingdom.
