Wiki: A 4th-century Roman signal station, one of several on the Yorkshire coast, was built on the headland at the cliff top. The station was to warn of approaching hostile vessels, and took advantage of a natural source of fresh water which became known as the "Well of Our Lady".[6] The remains of the signal tower were excavated in the 1920s revealing it to be square in plan around a small courtyard. It measured about 33 metres across and was built of wood on stone foundations with a gatehouse and an outer ditch.
