Castle: Tower of London - Ep 1

Medieval historian Marc Morris travels the length of Britain to tell the story of the nation's castles, consulting the Bayeux Tapestry and archaeological evidence to discover how they evolved over a 600-year period, and revealing that the traditional motte and bailey-style constructions were actually of foreign invention, developed by William the Conqueror and with the episode ending with the building of stone castles that includes the notorious Tower of London. © Discovery Civilisation
