Fred Dibnah's Magnificent Monuments, Places of Work (S1 E4)

Fred Dibnah continues his tour of Britain's great building feats with a look at our places of work. In Chatham he visits one of our oldest dockyards, while at Armley Mills in Leeds he discovers an early form of fireproofing. His journey takes him from a 1,000-year-old tithe barn in Sussex, where he tries his hand at thatching, to the symbol of modern architecture, the Lloyd's building.
