A multi-disciplinary chronology for Alt Clut, Castle Roack, Dumbarton

Abstract

Small scale excavations at this early British stronghold were performed as part of a long term research programme on early historic fortifications in Scotland (here listed). Historical, archaeological and 14C evidence are combined to produce a historical account, identify the fortification implied by Bede in 731, and attribute its destruction to the Vikings Olafr and Ivarr the Boneless in 870. The 14C dates are best read as implying construction after 600, possibly after 650. Au(adp)
