I collected over 10 lists of the greatest achievements of civil engineering of all time from books, magazines and the Internet and combined them into one meta-list. The results are below – every work of civil engineering that was on at least two of the original source lists, organized chronologically. Note that there is some overlap with the Best Architecture list. For the same list organized by rank (i.e., number of lists the item is on), go here.
