“The project is being undertaken by the Calton Hill Conservation Trust in partnership with Headland Archaeology, a firm with headquarters in Leith. It is thought that the prominence of Calton Hill would have made it a focus of human activity in years gone by, just as it is today. Despite this, very little is known about the history of the hill prior to the late 18th and early 19th century, which saw the construction of the Calton Hill Observatory and two separate monuments to the Napoleonic Wars.
The project will scrutinise the “archaeological potential” of the hill – indications of ancient human activity. The project will utilise “non-invasive” drone photogrammetry, the process of capturing many overlapping photographs of a desired target for 3D rendering. These examinations of the land and 3D models will be entered into a geographical information system (GIS) and compared to the historic record.”
