Barburgh Mill
The following information comes from David J.
Breeze ,and was published in the Journal Britannia in
1974:
"[the fort] measured 29·50 m by 28·50 m within its single
ditch and turf rampart. The entrance was defended by a gate of six
timbers probably surmounted by a tower. It contained two timber
buildings in plan appropriate for an infantry century. A latrine
lay in one corner of the fortlet and two possible hearths between
the two buildings. The fortlet was surrounded on the north and east
by an outer rampart and ditch and the resulting enclosure
subdivided by a medial ditch. The entrance of the outer enclosure
was undefended. There was only one structural phase represented at
the site and the pottery suggests a date in the Antonine I period,
c. 142-58. When the site was abandoned the buildings were probably
burnt, the rampart slighted and broken and surplus pottery dumped
in the ditches."
