For the next installment of 'The Post Hole meets...' we conducted an interview with the Deputy Vice Chancellor of The University of York, Dr Jane Grenville who specialises in heritage policy and the conservation of historic buildings. She discusses the application of the theory of ontological security to the conservation of the historic environment, something which has the potential to impact everyone. She also offers us a personal insight; how she came into archaeology, as well as the building that matters most to her and why.
