Bofors Anti-aircraft Gun
Hamble Common promises much but delivers very little. According to the display board This area is home to an Iron Age Settlement, a Tudor Castle, a 19th Century Gun Battery and a WWII Bofors Anti-aircraft Gun.
The only visible evidence of an Iron Age Settlement is a bank and ditch running across the neck of land between the creek and the shore, controlling access to what may have been an ancient landing place.
Hamble Oil Terminal
The only substantial remains, are those of the WWII Bofors Anti-aircraft Gun Platform. The actual gun was removed after the war, but a similar gun was installed in its place in 1989. Note: When I visited in 2018 the sea had badly undermined one end of the gun platform and the whole thing had been fenced off with substantial metal fencing that probably cost more that it would have done to repair the damage. Strange times we live in.
Adjoining the eastern edge of the common is BP's Oil Terminal which takes products from refineries by pipeline and by ship, and distributes them by pipeline and road tanker.
