So many stories are told about Dunluce Castle and its surrounds that it is hard to separate fact from fiction. Helen Mark visits the ruins on the north Antrim coast to try to establish some facts at the first major archaeological dig to be held there.
The archaeological team have been astounded by the wealth and quality of their finds, which include an entire lost merchants' town and the location of a 13th-century settlement.
Helen also goes underground to find how the sea caves and their legends have inspired a photographer to capture their image. But does Helen's experience of unexplained howls add more to the myths than to dispel them?
