This is the first ever definitive story of London?s City Wall which stretches just over two miles with about a third still remaining. Punctuated throughout by passages of London and British history across the centuries, this is the first ever book documenting the full story of London?s most ancient monument and how to access what survives above and below ground. Walking London Wall is a book of two parts. The first part charts the history of the wall and the important places associated with it following its route from west to east. The second part is a field guide for those who actually want to follow its course, starting at Blackfriars and ending at Tower Hill including, for the first time, an exploration of the Roman Riverside Wall, long a matter of debate and conjecture.
