The 7 Wonders of the World or Seven Wonders of the Ancient World represent the list of seven remarkable constructions of antiquity. Number seven was chosen because Greeks believe it as a symbol of perfection and efficiency.
• The first reference to a list of seven such monuments was given by Diodorus Siculus.
• The epigrammist, Antipater of Sidon gave a list of seven such monuments, including six of the present list (substituting the walls of Babylon for the lighthouse) who described the structures in a poem around 140 B.C.E.
• Philo of Byzantium, wrote a short account entitled The Seven Sights of the World. However, the incomplete surviving manuscript only covered six of the supposedly seven places, which agreed with Antipater’s list.
• Earlier and later lists by the historian Herodotus (484 BC–ca. 425 BC) and the architect Callimachus of Cyrene (ca. 305–240 BC), housed at the Museum of Alexandria, survived only as references.
History gives sanctity to the list of seven wonders that is compiled in 2nd Century BC by Philo of Byzantium, Greek mathematician.
The monuments that are featured in the ancient list include
- Great Pyramid of Giza, Egypt
- Colossus of Rhodes, Greece
- Hanging Gardens of Babylon, Iraq
- Lighthouse of Alexandria (Pharos of Alexandria), Egypt
- Mausoleum at Halicarnassus (Tomb of Mausolus), Turkey
- Statue of Zeus at Olympia, Greece
- Temple of Artemis (Artemision), Turkey
The only ancient world wonder that still exists is the Great Pyramid of Giza.
The tradition of Seven Wonders has inspired some writers from 19th and 20th centuries to come up with The Seven Wonders of the middle ages which include:
- Catacombs of Kom El Shoqafa, Egypt
- Colosseum, Italy
- Great Wall of China
- Hagia Sophia, Turkey
- Leaning Tower of Pisa, Italy
- Porcelain Tower of Nanjing, China
- Stonehenge, England
Later there was global movement to choose the new Seven Wonders of the World by structured international polling from 200 existing monuments which was led by Canadian-Swiss Bernard Weber and organized by the New 7 Wonders Foundation based in Zurich, Switzerland. The polling was open to all the people across the world. The campaign made it mandatory that the structures must be man made and be in sufficient state of preservation.
The new seven wonders of the world were announced on July 7, 2007 in Lisbon, Portugal.
The Great Pyramid of Giza, largest and oldest of the three pyramids at the Giza Necropolis in Egypt is the only monument picked from original Seven Wonders of the Ancient World and granted honorary status.
