Reasons for Designation
Hadrian's Wall marks one of the frontiers of the Roman Empire. The
international importance of the surviving remains has been recognised through
designation as a World Heritage Site.
The military importance of the Tyne-Solway route across the Pennines was
recognised by the Romans in the second half of the first century AD when a
military road, the Stanegate, was constructed along with a series of forts.
There is evidence that the Tyne-Solway route was being recognised as a
frontier by the start of the second century AD, but the line was consolidated
in the early second century AD by the construction of a substantial frontier
work, Hadrian's Wall, in c.120 AD. Subsequent attempts to establish the
boundary further north, between Clyde and Forth, failed by c.160 AD. Hadrian's
Wall then remained the frontier of the Roman Empire in Britain until c.400 AD
when Roman armies withdrew from Britain.
For most of its course, the 70 miles of Hadrian's Wall running from coast to
coast comprised a continuous stone wall (which in places was first temporarily
built of turf) with permanent structures sited at intervals of one Roman mile
(milecastles) and at third of a mile intervals (turrets) between the
milecastles. At a later date, the Wall was strengthened by 16 full-size
garrison forts built either on, or close to, the Wall. To the north of the
Wall, for most of its length, lay a substantial defensive ditch and to the
south a complex of banks and ditches provided east-west communication and
demarcated the frontier zone from the province.
To the west of Bowness-on-Solway, where the Wall reached the sea, however, the
frontier had a different character and served a slightly different purpose. At
the western end of the Wall a system of milefortlets and towers, spaced
similarly to the milecastles and turrets along the Wall, extended the frontier
system for at least 27 miles down the Cumbrian coast and helped control
movement across the estuary of the Solway Firth. In places these milefortlets
and towers were supplemented by lengths of palisade fences.
Throughout its long history the Wall was not always well maintained. It was
often neglected and sometimes overrun, but it remained in use until the late
fourth century when a weak and divided Roman Empire finally withdrew its
armies from the Wall and Britain.
The frontier works along the Cumbrian coast survive as earthworks or buried
archaeological remains, the latter sometimes visible on aerial photographs.
They survive in this form largely as a result of the more ephemeral materials
of which they were built (timber and turf instead of the stone of Hadrian's
Wall land frontier) rather than because of poor survival of archaeological
remains. Components of the coastal frontier which have surviving
archaeological remains, whether visible or not, will generally be considered
of national importance.
A combination of aerial photography and limited excavations have shown that buried remains of Biglands House milefortlet 1 and an associated defensive system of parallel ditches survive well. The monument will contribute to any further study of the Roman frontier defences along the Cumbrian coast.

The monument includes the buried remains of all but the south east corner of
Biglands House milefortlet together with the buried remains of a c.210m length
of the linear defensive system, here comprising parallel ditches aligned north
east-south west. The linear defensive system has been identified in part by
a combination of aerial photographs, excavation and geophysical survey
along the Cumbrian coast, but in particular between Bowness-on-Solway and the
northern shore of Moricambe. Within the sequence of milefortlets along the
Cumbrian coast this one has been identified as number 1. It was originally of
turf and timber construction and is located on the low ridge of a raised beach
adjacent to Campfield Marsh and Biglands House Farm. The milefortlet was first
identified from aerial photographs taken during the late 1940s which clearly
showed the crop marks of much of the milefortlet's infilled defensive ditch
enclosing a subrectangular area measuring c.50m north-south by 40m east-west.
Faint surface traces of this defensive ditch can still be seen. Limited
excavation by Bellhouse in 1954 located the milefortlet's east rampart. A more
extensive area excavation undertaken by Potter in 1975 found that the
milefortlet had undergone three main phases of occupation during the second
century AD. Phase I is dated c.AD 125-140 by the excavator; the milefortlet
was defended by a single ditch up to 4.5m wide and 1.5m deep and a turf
rampart c.7m wide. Access was by a gateway 3.6m wide and 1.6m long on the mid-
point of the north side through which ran a lightly metalled road. Internally
this earliest fortlet had a breadth of 14.5m and a length of approximately
20m. The principal surviving features were two cooking areas walled with turf
and set into the inner lip of the north rampart either side of the
milefortlet's entrance. Associated post holes suggest these features were
roofed, probably as a simple lean-to. Post holes and wall trenches
representing part of a rectangular structure, probably a barrack block, were
located to the east of the fortlet's central roadway while to the west of the
roadway a rectangular floored area measuring c.4.5m by 3m was interpreted as
the site of another barrack block. The Phase I occupation ended with the
deliberate demolition of the fortlet at a time consistent with the
construction of the Antonine frontier in Scotland, suggesting troops were
moved northwards from Cumbria to man the new frontier.
Phase II is dated c.AD 155-159; there is no closely datable archaeological
evidence, but the most appropriate historical context for this phase is the
brief re-commissioning of Hadrian's Wall by Roman troops in response to a
revolt in the Brigantian territory of northern England. The milefortlet was
rebuilt and again defended by the single ditch and a rampart, the latter with
timber revetting in front and a width of up to 6.5m. The gateway was built on
the lines of the earlier entrance, the principal difference being a much
thicker road surface. Internally the plan of the second period fortlet closely
followed that of the first; in the north east corner the turf-walled cooking
enclosure was replaced by a timber-built rectangular lean-to measuring 6.75m
by 3.7m. A hearth, an oven and scattered potsherds show that this was one of
the main cooking areas of the fortlet. Another hearth was found overlying the
Phase I cooking area in the north west corner, and faint traces of a
rectangular barrack block measuring up to 7m by 4m were found to the west of
the central road. This second occupation phase also ended with deliberate
demolition of the milefortlet at a time consistent with the Roman
re-occupation of southern Scotland and the Antonine Wall, and again suggests
that troops were moved northwards once more.
Phase III is dated c.AD 163-180 by a combination of Roman pottery and a coin.
This period coincides historically with the second Roman withdrawal from
Scotland. The milefortlet was rebuilt on a slightly smaller scale; it was
again defended by a ditch and rampart, the latter measuring up to 9.5m wide
and timber revetted at the front. A secondary ditch 1.5m wide and 0.35m deep
was cut between the rampart and ditch on the north side but may have
functioned as a drain rather than a defensive feature, and the gateway was
drastically remodelled into a narrow passageway 1.5m wide running diagonally
throught the rampart. Internally two hearths were found in the west side of
the fortlet but later ploughing has damaged some of the archaeological
deposits of this final period. However, a cluster of finds on the west side of
the central road suggests that this continued to form the main area of
activity occupied by a single barrack block. Historically the final
abandonment of Biglands may relate to the military campaigns of Ulpius
Marcellus, Roman governor of Britain in the early 180s, who fought the
northern native tribes at this time.
The associated parallel ditches were first identified on aerial photographs
taken in 1975. These showed the crop marks of two ditches c.46m apart running
across two fields to the north east and approaching the front and rear of the
milefortlet. Limited excavation showed that the forward ditch originally
measured c.1.5m wide by 0.8m deep and that it was subsequently recut on at
least two other occasions. The rearward ditch was of a simple single-phase
with a well-defined square `ankle-breaker' sump at its base.
All gateposts, post and wire fences, garden fences, a telegraph pole and the
surface of all paths and the farm track are excluded from the scheduling,
although, the ground beneath all these features is included.
