In this fascinating and innovative look at the underbelly of Victorian London, Paul Dobraszczyk offers a new account of how the citys sanitation was revolutionised in the 1850s and 1860s by means of gigantic new sewers and magnificent pumping stations. He focuses on the question of how these new spaces were understood and represented by both those who planned and promoted them (reformers and engineers) and also by those whom they impacted, namely Londons populace. Richly illustrated with maps, engineering drawings, newspaper engravings, and architectural photographs, this book suggests new ways of understanding Londons sewers and makes visible these vital, yet hidden spaces of the city.
