Wonders of the World

Various lists of the Wonders of the World have been compiled from antiquity to the present day, in order to catalogue the world's most spectacular natural features and human-built structures.

The Seven Wonders of the Ancient World is the oldest known list of this type, documenting the most iconic and remarkable human-made creations of classical antiquity; the canonical list was established in the 1572 Octo Mundi Miracula, based on classical sources which varied widely. The classical sources only include works located around the Mediterranean rim and in the ancient Near East. The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it reflected the number of planets known in ancient times (five) plus the Sun and Moon.
