Castles: Britain's Fortified History

Sam Willis traces the history of the British castle from its first appearance in 1066.

Sam Willis tells the story of the English ruler who left the most indelible mark on the castle -- the great Plantagenet king, Edward I who turned it into an instrument of colonization.

Sam Willis explores how, by the Wars of the Roses, castles were under attack from a new threat -- the cannon, but survived into the Tudor era only to find their whole purpose challenged.
