More than 650 landmarks are covered, ranging from ancient monuments such as Stonehenge, to contemporary engineering feats such as the World Trade Center in New York City. The concisely-written entries describe when the landmark was built, who built it, why it was built, its dimensions, how it was constructed, and any problems encountered during construction. Additional features include: numerous photographs; biographies of important builders and designers; glossary; chronology of dates in civil engineering from 3000 BC to the present; listings of tallest buildings, longest bridges, and highest dams, and a geographical index which locates the structures by country.
