(29) . East of Aldersgate Street. In 1922, during excavations on the site of the
Castle and Falcon Hotel and its yard in Aldersgate Street, a piece of the
wall was found running East and West. At the extreme East end of the property
about 210 feet East of the street was found a part of the angle-bastion and from
this point the wall was traced to Aldersgate Street. It remained in parts
undisturbed from the modem ground-level down to the foundations, a depth of
about 10 feet, and over its whole length the outer face had been repaired in
later Roman times.
The outer face, for about 20 feet West of the bastion, was badly battered. No trace of a Roman ditch was found. At one point a brick-lined drain pierced the wall.
