On the surface, Southwold’s geology seems simple. The sea is trying to reclaim the large banks and areas of sand around the town, and it’s often a case of a battle between the two. There’s also quite a few chunky gravel pits near the town, which provide a certain resistance and stability against the sea’s ravages.
There’s more to it than that, though. The geology of Southwold owes itself largely to about 2 million years ago, when the sea’s constant backwards and forwards movement resulted in an odd set of geological arrangements. In an unusual style of beach formation, Southwold had many islands to it, and the sea flowed through these and created the other set of gravel pits that can be found there today.
