The castles of Britain are icons of history. They were built to mark the domains of the powerful and stood as symbols of authority. They were built using the most advanced structural technology of the day and were designed to withstand the strongest of attacks. And their locations illustrate the understanding of how the lie of the land and a good position would assist their joint roles as defenders and emblems of power And no view of great castles is as imposing and revealing as the view from above -showing off their beauty, highlighting their purpose, focusing on their extraordinary design. Castles From the Air shows the splendour and lasting resonance of the nation's best-loved castles.
