TM5075 : The Dunes south of SouthwoldAlthough these are undoubtedly dunes, the area is marked "The Denes" on the map. This is exactly where the sea broke through in the 1953 floods, with loss of life: the occupants of "Blue Posts" in this area. I was at boarding school on Southwold Common and woke to find the view from the window, previously marshland, was sea all the way to Walberswick, itself partly submerged.
