The streetscape of London’s historic square mile has been evolving for centuries, but the City’s busy commercial heart still boasts an extensive network of narrow passages and alleyways, secret squares and half-hidden courtyards. Using his wealth of local knowledge, historian David Long guides you through these ancient rights of passage – many dating back to medieval times or earlier – their evocative names recalling old taverns, notable individuals and City traditions. Hidden behind the glass, steel and stone of London’s banks and big business, these survivors of modern development bear witness to nearly 2,000 years of British history.
