- LAA Emplacement: DoB ID: e42025 RAF Mona was built on the site of the former WWI RNAS airship station, and was the last airfield to be built on Anglesey being officially opened in December 1942 under Flying Training Command. No. 3 Air Gunnery School was transferred here from Castle Kennedy the same month, flying in Bothas supplemented by a number of Battle and Martinet aircraft. Today it is still an active airfield that acts as a Relief Landing Ground (RLG) for RAF Valley's jet training aircraft. Few of the WWII defences remain, this brick-built circular gun pit is one of two such structures, this one is located to the northwest of the large T1 hangar, itself a relic of WWII. The entrance to the gun pit has a free standing brick-built blast wall in front of it. SH4175 : North Wales WWII defences: RAF Mona, Anglesey - LAA Emplacement (2)
