This lies buried between to two Napoleonic defensive Martello-Towers that overlook the sheltered East Wear Bay, and some of the most productive and interesting fossil beds in the UK. The geology of the area is quite interesting with a sequence of varying rock types along a couple of miles of seashore.

The earliest rocks at Folkestone consist of Lower Greensand exposed to the north of the town and run through a sequence of Lower Greensand, Gault Clay (phasing into Upper Greensand) and Chalk, the whole sequence dating from approximately 120 to 80 million years old. The chalk increases in thickness to the north culminating with the famous white cliffs of Dover before dipping off to the north approaching Deal. The complex geology of the area has caused landslips, the impervious clay sandwiched between the Lower Greensand and the chalk has been known to slip under the enormous pressure causing landslides in an area known as 'The Warren'; it is alleged that the railway line that cuts through this area en route to London is extremely expensive to maintain due to the...
