This is the story of Britain’s islands and how they are woven into its culture, history and collective psyche. From Neolithic Orkney and druidical Anglesey to the joys and strangeness of modern Thanet, we explore the furthest reaches of Britain’s island topography, once known by the collective term, Britanniae (the Britains). Alice Albinia takes the reader over borders and through disparate island cultures, past and present, listening to neglected voices and subversive stories. ‘The Britannias’ examines how the smaller islands have wielded disproportionate influence on the mainland, becoming the fertile ground of political, cultural and technological innovations which have gone on to change history throughout the archipelago.
