An area of Mitcham Common that is south of the Mitcham Junction tramstop and railway station, east of the Carshalton Road, and is bounded on its eastern edge by the railway line between Mitcham Junction and Hackbridge stations, and on its southern edge by the scaffolding yards at the rear of the Corporation Cottages.
The area is called the Gunsite after its use during WW2 as an anti-aircraft installation, as shown on this 1955 OS map:

Currently, the area shows no sign of its wartime use.
This board has no date and doesn’t mention the WW2 use of the area, however on the Conservator’s website, suggested walk no. 2, ‘Between The Tramstops’ (pdf) says:
… the area is known as the Gunsite because six anti-aircraft guns were stationed here during the second world war. The troop quarters were still present in the mid-1950s when they were used to house local people while new estates were being built in Mitcham.
The text on the info board:
Mitcham Common is a 180 hectare site of Metropolitan Importance for nature conservation that is one of the most interesting and varied open spaces in south London. It supports a range of habitat types which include secondary woodland and scrub, ponds and other wetland features, together with large tracks of natural grassland and smaller parcels of the regionally important acid grassland and heathland habitats. Together these are home for a vast array of plants and animals many of which are locally rare. In order to maintain this biodiversity the Common requires active management which is undertaken by full-time staff assisted by local volunteers.
The Common is managed and regulated by the Mitcham Common Conservators who are a statutory corporation empowered under the Metropolitan Commons (Mitcham) Supplemental Act 1891.

Gun-site families to change huts
The regrouping of families living at the gun site in Carshalton-road, near Mitcham Junction, will cost £1,000. The War Office, who want to clear up part of the site, have asked that the families should move into huts on the north side of the entrance road to the site. The condition of the huts the, people will move into is poor, say Mitcham Council. It is the conversion of the huts which will cost the money. Mitcham have agreed to the proposal on condition that the Ministry of Housing pay the cost of conversion.
Memories
Discussion on the Facebook Mitcham History Group led to these memories being recalled:
Carole said
… dad used to talk about the house opposite that had had its roof damaged and repaired so many times that they had V for victory in morse code in the tiles on the roof. Sadly, it was removed when re-roofed.
Eddie said
Happy memories as a kid playing there.
Isabella said
I was born on the gun site in 1947, lived there until 1954. I had a fantastic childhood growing up there.
Pat said
My brothers used to play there.
One night the whole of Pollards was out till 9pm looking for one of them ( he’d got carried away playing & forgot the time).
Another time my mum was cleaning under his bed & found a tin with hand grenades & bullets in it….she went with him to the police station and they had to have them blown up by the army. To say we’re lucky to be alive, is an understatement.
Terence said
I was born there in the old mess hut

Ah yes. The old gun site. My first memory of it was seeing the actual guns being used in practice after the war by the soldiers still manning it. Afterwards was it was completely different as a place to play on. With tunnels to the gun pits where the guns once stood. Happy days.
