The report on excavations which took place in 2001/02 in advance of the construction of a bypass in Buckinghamshire. Features uncovered include a site with evidence for Bronze Age activity, a later site with an Iron Age roundhouse and an Iron Age/Roman trackway, and a third site with late Iron Age enclosure ditches and post-holes as well as a dispersed early Saxon cemetery. Overall the project added most to our understanding of the prehistoric landscape, and its survival into medieval parishes.

The frontiers of the Roman Empire together form the largest monument of one of the world's greatest ancient states. They stretch for some 7,500 km through 20 countries which encircle the Mediterranean Sea. The remains of these frontiers have been studied by visitors and later by archaeologists for several centuries. Many of the inscriptions and sculptures, weapons, pottery and artefacts created and used by the soldiers and civilians who lived on the frontier can be seen in museums. Equally evocative of the lost might of Rome are the physical remains of the frontiers themselves. The aim of this series of books is not only to inform the interested visitor about the history of the frontiers but to act as a guidebook as well. The remains of the Roman frontiers in Wales are unique in the Roman Empire. Unlike the well-known defensive linear boundaries such as Hadrian's Wall and the Antonine Wall in northern Britain, the forts and fortresses in Wales formed a dynamic offensive frontier designed to deal with the fierce natives. More than 60 stone and timber fortresses, forts and fortlets are known, some of which seem to have been occupied for only a few years, while others remained in use for far longer. They tell the story of the long and brutal war against the Celtic tribes and, after their final and complete victory, the army's policy of 'occupation-in-depth' when up to 25,000 legionaries and auxiliaries were stationed in Wales. We hope the readers of this book will enjoy discovering the fascinating story of the Roman conquest of Wales almost 2,000 years ago.
