Liddel Strength

Liddel Strength is an ancient monument near Carwinley, Cumbria, in northwest England. It consists of the earthwork remains of an Anglo-Norman border fortification (the seat of the barony of Liddel) destroyed by the Scots in 1346 (a wooden motte and bailey castle at the time of its destruction; possibly earlier a ringwork) and fragmentary remains of a pele tower subsequently built upon the site. It lies on a cliff on the south bank of the Liddel Water, overlooking the Liddel Water's confluence with the River Esk; the last high ground before the Esk reaches the Solway Plain. The Liddel Water (upstream of the confluence) and the Esk (downstream) form the modern Anglo-Scottish border; formerly they were the southern boundary of the Debatable Lands.
