Underground Liverpool is a fascinating account of this body below the skin. Liverpool is honeycombed with tunnels, cellars and subterranean oddities and, because no map exists, this book is a unique attempt to reveal the secrets of this strange world. The familiar, such as the two road tunnels, contrasts with the mysterious working of the eccentric Mole of Edge Hill. Public utilities, such as water, gas and electricity, are relatively well-known but what of the hydraulic and pneumatic systems that criss-cross the city centre? The Cavern Club is world famous but who knows about the strange cells beneath a bookshop in Fazakerley Street, or the tunnel cut into sandstone that runs the length of James Street from the site of the old castle? Underground Liverpool is an eye-opening account into this forgotten world beneath our feet.
