The notion of the Seven Wonders of the Ancient World can be
traced back to the fifth century B.C. These creations rivaled
many created by nature in their size, majesty, and beauty. Six
of the seven wonders no longer stand, having been destroyed by
natural disaster or by humans.
Note: The idea of the list dates to the fifth century B.C.
when Greek historian Herodotus marvelled about some of the
Wonders. Although it has been argued that other ancient
wonders of comparable regard—such as the Great Wall of
China, Machu Picchu in Peru, and the Aztec Temple in
Tenochtitlan in Mexico—should have been included, these
may not have been known about by the Greeks who first proposed
Wonders for the list.
