According to the St. Ives Archive Centre the post lies in a heavily overgrown enclosure behind Trewartha House to the east of a farm track.
Despite being described as still intact in 2000 no trace could be found during an inspection of the site.
The concrete base of the wartime post 35 metres from Knill Monument (SW51593870) can still be seen. It is in the middle of a footpath to the monument.
Opened in 1962 and closed in 1968.
