Architecture, Regional Identity and Power in the Iron Age Landscapes of Mid Wales: The Hillforts of North Ceredigion by Toby Driver.

"This is a study of the Iron Age hillforts of north Ceredigion (Cardiganshire), mid Wales. Over one hundred diverse and unusual hillforts and defended enclosures are known in this topographically distinctive landscape, framed between the west coast of Cardigan Bay and the eastern high ground of the Cambrian Mountains. This new research sheds light on their architecture, chronology and the dynamic use of the regional terrain in later prehistory, reaching conclusions that have resonance for the wider study of British hillforts."
