7 Wonders of the World

Various lists of the Wonders of the World have been compiled from antiquity to the present day, to catalogue the world's most spectacular natural wonders and manmade structures.

The Seven Wonders of the Ancient World is the first known list of the most remarkable creations of classical antiquity, and was based on guide-books popular among Hellenic sight-seers and only includes works located around the Mediterranean rim. The number seven was chosen because the Greeks believed it to be the representation of perfection and plenty.[1] Many similar lists have been made.

The historian Herodotus (484 – ca. 425 BCE), and the scholar Callimachus of Cyrene (ca. 305 – 240 BCE) at the Museum of Alexandria, made early lists of seven wonders but their writings have not survived, except as references. The seven wonders included:

Great Pyramid of Giza
Hanging Gardens of Babylon
Statue of Zeus at Olympia
Temple of Artemis at Ephesus
Mausoleum of Maussollos at Halicarnassus
Colossus of Rhodes
Lighthouse of Alexandria

The earliest lists had the Ishtar Gate as the seventh wonder of the world instead of the Lighthouse of Alexandria.

The list known today was compiled in the Middle Ages—by which time many of the sites were no longer in existence. Today, the only ancient world wonder that still exists is the Great Pyramid of Giza.
