The final episode follows the changing fortunes of a heritage movement floored by the after effects of World War II and looks at how people like Sir John Betjeman and Dan Cruickshank gave families access to heritage and architecture on television from the comfort of their living rooms. It looks at the preservation of sometimes ugly, certainly unpleasant parts of our built past such as workhouses and underground mineshafts, and contemplates what the future may hold for heritage in Britain - a nation faced with economic uncertainty, depleting resources and increasing challenges of sustainability.
