An editied selection from a series of interpretation panels placed on two sites. In the case of the Dover panels only traces of the original man-made structures remain today. The Dover project included the research, design - using the new National Trust branding - and illustration of the panels. The cutaway images are based on the research, a site visit and contemporary photographs. Some aspects of the illustrations are conjecture formed from the limited information that is available. The remaining panels were for Quebec House, Westerham.
