This body of acquired knowledge can be thought of as cultural tradition, and varies from place to place, helping to foster a sense of identity from family to village to school or larger unit, such as a country. It is more widely known under the name of folklore.
In the following pages, with the help of John Billingsley, we hope to give you a flavour of the stories that are still told in Calderdale communities in the surrounding areas.

Upper Calderdale's suitability for the preservation of local cultural tradition is nowhere shown as strongly as in its wealth of folk tales about places, many of which are still being passed on by word of mouth.
For some years now a small group of friends has been exploring the evidence for prehistoric activity in the South Pennines.
