In June, we look at our military defence: our coast was the frontline whenever invasion threatened. Examples of Roman “Saxon Shore” forts and 19th-century Martello towers still survive, as do remains of our defences in WWI and WWII such as pill boxes, anti-tank obstacles and coastal batteries. These are now under threat again, not by hostile armies, but from a ferocious sea.
