The town's name changed to
Burgh
from the late tenth century, possibly after Abbot Kenulf had built a defensive
wall around the abbey, and eventually developed into the form Peterborough; the
town does not appear to have been a borough until the 12th century. The
contrasting form
Gildenburgh is
also found in the 12th century history of the abbey, the Peterborough version
of the
Anglo-Saxon Chronicle and in a history of the abbey by the monk
Hugh Candidus.
