During World War II, Carne Beacon became the site of the very first Cornish above ground aircraft reporting post. It opened in January 1940 as part of No 20 Group Truro and was designated the name of T2 Veryan Post. The site was chosen because of its advantageous views over the sea. Local residents strongly objected to its placing on such a hallowed (archeological) point but they were overruled by the Air Ministry. The view was excellent for this post which was a wooden structure some 3 metres by 4 metres square. The post consisted of an observation area with aircraft plotting instrument and a small space for making refreshments and gaining shelter. They communicated by a land line telephone to Truro where the main operations room was based. It was later refurbished with concrete and remained in use after the war mainly manned in villagers spare time. In 1962 the site closed and moved to Nare Head. The site was demolished and some remains are viewable at the Veryan Post Museum. In present day all that remains of the post are its concrete foundations.
