London Clay: Tom Chivers in Conversation with Dr Rebecca Wragg Sykes

Celebrate London and delve deep inside the nooks and crannies of a forgotten city: a hidden landscape long buried underneath the sprawling metropolis. Armed with just his tattered Streetfinder map, author Tom Chivers follows concealed pathways and explores lost islands, to uncover the geological mysteries that burst up through the pavement and bubble to the surface of our streets.

From Roman ruins to a submerged playhouse, abandoned Tube stations to ancient riverbeds, marshes and woodlands, this network of journeys combines to produce a compelling interrogation of London's past. London Clay examines landscape and our connection to place, and celebrates urban edgelands: in-between spaces where the natural world and the city mingle, and where ghosts of the deep past can be felt as a buzzing in the skull. It is also a personal account of growing up in London, and of overcoming loss through the layered stories of the capital.
