Research Interests

Mark Lewis's research interests centre on the study and use of material culture to understand and further our knowledge of the past. His involvement with field archaeology for over 30 years and his academic background in archaeological conservation and conservation science bring an artefact and artefact technology (materials science) perspective to his approach to the sphere of museum studies. His undergraduate study of prehistory at Cardiff University under Professors John Evans, Alistair Whittle and Niall Sharples nurtured a phenomenological, landscape, approach to the macro-scale interpretation of the geography of the past. Employment with Amgueddfa Cymru – National Museum Wales since 2001 has given a museological emphasis to research into informal learning in archaeology through the museum setting, online and through visits to monuments cared for by the state. His current research focus remains broad-based but centres on the Roman archaeology of Caerleon, its context (including its relationship to Caerwent), and its role within and beyond the western frontier zone of Britannia. A museological strand of this research will focus on presenting Roman pasts to non-specialist audiences. Mark is currently working with Dr Peter Guest, Senior Lecturer in Roman Archaeology at Cardiff University on a jointly-authored book about the Roman legionary fortress at Caerleon.

Career Overview

Mark Lewis was born and raised in Monmouthshire and his interest in archaeology was nurtured during family walks in the south of the county and whilst working on excavations during the 1980s and 1990s at Trostrey and Caerwent. He read archaeological conservation and conservation at Cardiff University. There he was awarded a PhD for his research on humidity and iron corrosion which informed the preservation strategy for Brunel's ss Great Britain and now informs the preservation of museum artefacts and structures, such as the Severn Bridge, worldwide. Since 2000, he has been a curatorial officer and senior curator at the National Roman Legion Museum, Caerleon, and from 2006-14 he was also an archaeological conservator at Amgueddfa Cymru - National Museum Wales, Cathays Park, Cardiff. He was Chairman of the Monmouthshire Antiquarian Association from 2013-16. From 2013-17 he was Chairman of the Glamorgan-Gwent Archaeological Trust, having been a Trustee since November 2008. In 2016 he was elected a Fellow of the Society of Antiquaries of London. He has regularly contributed to undergraduate and postgraduate teaching at Cardiff University and the University of South Wales, as well as contributing towards the regular hosting of museum internships from University College London and Durham University, with museum placements hosted for students from institutions far and wide, e.g. from Newport and Cardiff to The University of Queensland, Australia
