London's story weaves in and out of places where some vestige of the past remains: the medieval wall, the preserved timbers of the Roman dock-side; the crypts of the churches where you can trace the bricks and mortar of Saxon and medieval predecessors; and a wealth of 17th-century architecture preserved in the 40-odd churches designed by Wren after the Great Fire. This book takes readers on an illustrated tour through the main chapters of the capital's history, and its architectural and archaeological gems.
