Discovery, Innovation and Science in the Historic Environment RESEARCH ISSUE 8 . SPRING 2018 ...to a new look for the magazine. In this issue of Historic England Research we offer another exciting range of applied research stories showing the stunning breadth and depth of our historic environment. Lidar technology reveals a Lancashire hillfort that isn’t, while thermography uncovers the energy efficiency of historic buildings and detects sources of moisture ingress. We look at a castle ‘at risk’ on the Welsh borders that, with the commitment of the local community is being rediscovered, repaired and, with research by Historic England, reconnected with its original landscape. We rediscover the parish poorhouse of Framlingham Castle and look at how research is helping develop Local Lists in Nottingham. We review the results of a study we funded on major parish churches and the particular challenges they face, explore Welcome... the past and possible future of climate change, and reconsider the wreck of HMS Colossus, both in the Isles of Scilly. Finally, we explore how through our funding the Cambridge Archaeological Unit published the final volume of the seminal excavations at Mucking, Essex. This volume provides the perfect opportunity to mark the retirement of Steve Trow, a long standing member of Historic England and Director of Research, under whose watch many of these projects happened.
