Whether you are seeking to know London better, or are already an expert or guide, this book is immensely satisfying.
It has chapters covering first, the general history of the buildings, and then under topics such as "Markets", etc. The whole range of artchitecture, both ancient and contemporary, is addressed with engaging, informed writing and gorgeous photographs.
Then the authors move on to twelve walks not only the City of London and the West End but outlying areas such as Greenwich (south of the river) and Hampstead (up in northwest London).
Of course the book is a gift to all London professionals or guides, who will find their enthusiasm fired and their knowledge freshened. It's a coffee-table-top item but unlikely to sit around gathering dust. Although too heavy to take out on the street, it's highly usable. For novices or people who haven't been, the readable text and beautiful pictures will whet your appetite.
