"Although most people know that a list exists of the Seven World Wonders, only few can name them. The list of the Seven Wonders of the Ancient World was originally compiled around the second century BC. The first reference to the idea is found in History of Herodotus as long ago as the 5th century BC. Decades later, Greek historians wrote about the greatest monuments at the time. Callimachus of Cyrene (305BC-240BC), Chief Librarian of the Alexandria Mouseion, wrote "A Collection of Wonders around the World". All we know about the collection is its title, for it was destroyed with the Alexandria Library.
The final list of the Seven Wonders was compiled during the Middle Ages. The list comprised the seven most impressive monuments of the Ancient World, some of which barely survived to the Middle Ages. Others did not even co-exist. Among the oldest references to the canonical list are the engravings by the Dutch artist Maerten van Heemskerck (1498-1574), and Johann Fischer von Erlach's History of Architecture."
One still stands. One has recently been re-discovered. Four are lost to antiquity. One may never have even existed. They are the Seven Wonders of the Ancient World. Learn all about these structures, each built over 2,000 years ago, which became known as the greatest creations of mankind. The Seven Wonders of the Ancient World
