In the early evening of 16 October 1834, to the horror of bystanders, a huge ball of fire exploded through the roof of the Houses of Parliament, creating a blaze so enormous that it could be seen by the King and Queen at Windsor, and from stagecoaches on top of the South Downs. In front of hundreds of thousands of witnesses the great conflagration destroyed Parliament's glorious old buildings and their contents. The events of that October day in 1834 were as shocking and significant to contemporaries as the death of Princess Diana was to us at the end of the 20th century - yet today this national catastrophe is a forgotten disaster, not least because Barry and Pugin's monumental new Palace of Westminster has obliterated all memory of its 800 year-old predecessor. In this, the first full-length book on the subject, Parliamentary Archivist Caroline Shenton unfolds the gripping story of the fire over the course of that fateful day and night. In the process, she paints a skilful portrait of the political and social context of the time.
