Alleyways have a habit of leading to unexpected places. They act as the city's library: echoing the routes of trade, lost rivers, burial roads, disputed boundaries, tracks of animals and people. They hold the stories of a city that otherwise can no longer be seen. This map, by Matthew Turner, with original photography by Nigel Green, is an entry point to this story, introducing the hidden passages of London.
