The monument is a section of the linear boundary known as Scots Dyke situated
on level ground, to the east of Park House. The dyke includes a well preserved
bank and a shallow flanking ditch extending for 105m north to south. The bank
is 12m wide and is up to 2.5m high, with the ditch lying to the east being
1.5m wide. At the southern end, the line of the dyke continuing to the south,
can be identified in field boundaries but has been much altered by
agricultural activity and is not included in the scheduling. However 150m to
the south, the dyke continues as an earthwork where it is the subject of a
separate scheduling. At the north end the dyke has been truncated by a road
and there is currently no evidence that the dyke extended any further to the

The site of the monument is shown on the attached map extract.
It includes a 2 metre boundary around the archaeological features,
considered to be essential for the monument's support and preservation.

Reasons for Scheduling

Scots Dyke is a linear earthwork extending for 14km from the River Swale to
the River Tees in North Yorkshire. Significant sections remain visible as
upstanding earthworks and indicate that the dyke system had an earthen
rampart flanked on the eastern side by a ditch. Where not preserved as an
upstanding monument, the dyke is visible as a cropmark on aerial photographs
and elswhere often survives as a low bank beneath present field boundaries. It
was constructed in the post Roman period and encloses an area in the eastern
foothills of the Pennines between the two rivers. This area contained wealthy
arable and pastoral land as well as some of the mineral resources of the
northern Pennines. Linear earthworks were used to divide territory for
military, social, economic and political purposes, often using natural
features such as rivers and watersheds to define an area. Scots Dyke was built
to consolidate territorial and economic units in response to changing
political circumstances during the sixth and seventh centuries AD. These were
brought about, at least in part, by the arrival of the Anglians in northern
England. Fewer than 50 examples of linear earthworks of post Roman date have
been identified in England. As a rare monument type of considerable importance
to the study of early medieval territorial patterns, all surviving examples
are identified as being of national importance. This section of Scots Dyke
survives well and significant archaeological remains will be preserved which
offer important information about the development of the landscape in the post
Roman period.
