Catrail
Archaeological linear earthwork in Scotland / From Wikipedia, the free encyclopedia
The Catrail is a linear earthwork in Roxburghshire, southern Scotland.[1] It runs from Robert's Linn (55°18′56.7″N 2°43′47.56″W), a burn (stream) flowing into the Slitrig Water, westward and north-westward to the head of the Dean Burn (55°24′3.74″N 2°59′0.18″W), a tributary of the Borthwick Water. It is about 11.5 mi (18.5 km) long (as the crow flies), and consists of a ditch and bank. The Deil's Dyke was once considered to extend to the Catrail.
