Addinston Fort

Addinston Fort from "Sekirkshire" by Walter Elliot

We know more about Aethelfrith, grandson of Ida, who had built up his kingdom until it was strong enough to beat the Christian Gododdin at Catterick in 600 and the Christian Scots of Dalriada at Degsastan,* which is either Dawston in Liddesdale or more likely Addinston in Lauderdale, in 603.
