Founded to preserve and provide access to places of natural beauty or historical significance, the National Trust is one of the world's leading conservation organisations dedicated to preserving Britain's landscape. From ancient forests to historic houses and gardens, the Trust looks after more than a quarter of a million hectares of land, including over 770 miles of coastline and thousands of archaeological monuments across England, Wales and Northern Ireland. Anna Groves is a freelance journalist and author. She is the co-author of the National Trust Tour of Britain and has written official guidebooks to a number of National Trust properties, including a guide to its sheds. This is her first journey into the supernatural side of Britain's past and present.
