"Could archaeologists be about to uncover an early Bronze Age settlement on the cliffs of Seven Sisters?"
From the article, it is thought by archaeologist that a large Early Bronze Age settlement was located in the vicinity of the Seven Sisters cliffs.
An excavation project begins today near the cliffs' edges and runs about two weeks. There is probably some added sense of urgency to identify ancient materials since this year saw a major landslide of one of the cliffs [here].
