Shilla And Bog Head Bastles, Kielder Forest, Northumberland- Fabric Survey

Oxford Archaeology North (OA North) was invited by Jonathon Farries, of the Forestry Commission, to undertake an accurate fabric survey of the Shilla Hill (NY 7636 9038) and Bog Head (NY 7615 9099) bastles, Kielder Forest, Northumberland. Both structures are listed on the English Heritage (EH) Buildings at Risk register and, accordingly, English Heritage issued a brief for a programme of rectified photographic survey to be undertaken on each of the buildings (dated 23/01/07). A project design (OA North 2007) was compiled by OA North in accordance with the brief. The field survey was undertaken in March 2007.
The elevations of the bastles were recorded by rectified photography with respect to a survey control established using a total station. The images were scanned and any residual distortion within the photographic base was removed by digital correction using Photoplan software. Elevation drawings were produced within AutoCAD with respect to these images and have been submitted in accordance with the brief and project design.
