This chapter considers what ‘intangible’ means in the landscape by exploring interactions between humans and natural processes and the heritage this creates. Many commentators remark on the ‘slippery’ notion of landscape (Stilgoe, 1982; Benson and Roe, 2007) and the subsequent difficulty in building common understandings of the significance and meanings of landscapes between different academic disciplines, communities, professionals, cultures and groups. The complex idea of intangibility provides further difficulties to those who prefer neat definitions and notions. However, another view is to consider that through an exploration of the different conceptualizations of and links between intangibility and landscape, a richness can be revealed that allows for many different meanings to be expressed and opportunities for developing further understandings of both landscape and heritage.
