The end of a promontory, 1.5km long, protruding into the North Sea. The headland, Carr Naze, has attracted humans for thousands of years. Prehistoric flint tools have been found and the remains of a Roman watchtower. It is estimated the watchtower was 20m square and stood on a neck of land now a mere 3m wide. Such is the amount of erosion that has occured over the last two millenia.
