This book acts as a stimulus to further debate and discussion about the archaeology and architecture of the medieval diocese of Llandaff. It presents work at Cardiff and Skenfrith castles and focuses on buildings at Caldicot and Raglan.

The Association's 2004 conference focused mainly on the architecture and archaeology of the medieval diocese of Llandaff, comprising much of the historic counties of Glamorgan and Monmouthshire. Contributors consider Roman and early medieval south-east Wales, including surviving Christian monuments and the early history of Cardiff.
