When I picked up this book, I expected it to be a collection of 50 popular world monuments with pictures and information. However, it actually turned out to be a collection of erudite essays pertaining to important challenges facing preservation of monuments in the world currently - whether it is due to natural disasters, rapid urbanization, war and related political reasons, etc. Using that framing, the book talks about 50 monument sites across the world, outlining the efforts by World Monuments Fund in preserving them and the ongoing challenges. The layout design of the pages could have been much better, it was largely confusing to follow the essay while also reading about the interspersed monument details.
