Introductions to Heritage Assets (Designed Landscapes)
What IHAs cover
IHAs typically share a common approach, headings and format.
A short Introduction defines the asset type, notes any alternative names by which it is known, gives the broad date range, and discusses the distribution and number of known examples.
Next comes a Description, or Historical background, which considers in greater detail the structures' locations, their form and plan, and how they functioned.
With more complex asset types there may be a separate section on Chronology, tracing their development through time. Where relevant, a final narrative section identifies particular threats to the type.
Each IHA is concluded by a narrative guide to Further Reading, which signposts key works, especially those of an accessible character.
On 1 April 2015 the part of English Heritage represented on this website changed its name to Historic England. You may notice that some of our content still refers to English Heritage. We are in the process of rebranding, but in the meantime please be assured that all our content and guidance is still current.
