While out on Southampton Water on our recent Paddle Steamer trip on the Waverley I spotted a bunker that I had not noticed before between where the mouth of the River Hamble meets Southampton Water and the old Netley Hospital site. I decided to try and visit this relic of WW2 Parking at Netley Country Park I walked along the wooded shoreline and found the bunker. A 3 level bunker of a non standard design. On the ground floor defensive machine gun slots and the 2nd floor what appears to be an observation level with large slit window (now blocked up) and on the top floor a small square pillbox type structure. Constructed of thick concrete with no external stairs. There was no apparent door in the structure.
