Parts of these buildings date back to the royal palace, and evidence for a plantation from this period was also found. Painted window glass from both the royal and monastic occupations is reported on in detail in this volume, together with the many other finds left behind by the site's occupants, such as pottery and writing instruments. Finally, underlying the medieval remains, was a Bronze Age barrow or burial mound some thirty metres in diameter, its circular ditch presaging the rotunda of the new library which was to be built more than 3000 years later.
