Shidlaw Tower: In the early 1500's, the Prior of Kirkham Priory provided the villagers of Carham with a "little tower of defence against the Scots, of no real strength, without Barmekyn* or iron gate, intended for emergency refuge". It lasted less than 50 years. The tower and it's site are lost without trace. Probably the same as Carham Pele Tower.
*Barmekyn (Barmekin; Barmkin, or Barnekin): A medieval defensive enclosure found around smaller castles, Tower houses, Pele towers and Bastle houses in Scotland. As well as a residence, outbuildings were also included, plus a place to protect livestock during cattle raids. From the Roman Barbican, meaning an outer fortification of a city or castle.
