The original lighthouse, built in 1832, was on top of the cliffs but the cliffs being of soft chalk are rapidly eroding and the old light was getting dangerously close to the edge. To build a new light further back from the edge wasn't practical as the ground slopes down from the edge and the lighthouse would have had to be very tall to been seen from out at sea., so they built it at the bottom of the cliff, it was finished in 1902.
Not like Split Rock lighthouse where they had to dynamite the hard rock cliff for the foundations. Interesting, Graham. Thanks.
