In this book, author Alan Brooke highlights the historic gates of the City of London: Cripplegate, Aldgate, Aldersgate, Bishopsgate, Ludgate, Newgate and Moorgate. Originating in Roman times, they remained until they were all demolished between 1760 and 1767. Blue plaques mark six of their sites, and a bishop's mitre on a building shows where Bishopsgate once stood.

This book examines the history of the gates, with chapters devoted to each one. A shorter section offers a summary of some of the water gates on the River Thames, including Billingsgate and Bridge Gate, where goods were unloaded from ships. Additionally, there were pedestrian-only gates such as Tower Gate and the postern gate at the Tower of London. There were also the Bars, the most famous of which is Temple Bar, which can still be seen at Paternoster Square.

Illustrated throughout with archive material, photographs of present-day locations and a map, Gates of the City of London provides an important addition to the many books on London's rich and diverse history.
