This is kind of halfway inbetween a coffee table book and a travel book.  It's a hardback book of a less than A4 size filled with some of our world's greatest wonders split into two sections: natural and man made.  The man made are roughly in chronological order and go from caves painted by ice age people to the Burj Khalifa.  Each wonder begins with a tantalising introduction what it is like to encounter the wonder, a full page photograph, and 'how to get there' and what to do 'while you're there' sections.  Then follows a section on the construction and history of the wonder with 'did you know' boxes and great little diagrams.  It's informative and good to look at.

So why only three stars, well, because this book is neither one thing nor another.  The 'what to do while you're there' sections suggest a travel book, but this is really too heavy to be carried unless you are travelling by car.  The construction sections are good but so brief, too brief for me, it is not really big or detailed enough to be the kind of book you could devour at your leisure at home either.
