Seven Wonders of the World- In Case you ever wondered

(Posted by popular demand from Wikipedia)

The Seven Wonders of the World (or the Seven Wonders of the Ancient World) is a widely-known list of seven remarkable constructions of classical antiquity. The earliest known version of the list was compiled in the 2nd century BC by Antipater of Sidon; it appears to be based on the guide-books popular among Hellenic sight-seers and only includes works located around the Mediterranean rim.

The Seven Wonders
Listed in order of their construction, the seven wonders are:

Great Pyramid of Giza 2550 BC Egyptians
Hanging Gardens of Babylon 600 BC Babylonians
Statue of Zeus at Olympia 435 BC ancient Greeks
Temple of Artemis at Ephesus 550 BC ancient Greeks
Mausoleum of Maussollos at Halicarnassus 351 BC Hellenized Carians
Colossus of Rhodes 292-280 BC Hellenistic civilization
Lighthouse of Alexandria 3rd century BC Hellenistic civilization

In the tradition of the Seven Wonders of the Ancient World, many other lists of wonders have been proposed, including both human feats of engineering and wonders of nature. However, these lists are rather informal, and there is no consensus on any particular list.

Modern wonders
The following list of the top seven existing wonders was compiled by Hillman Wonders:

Great Pyramid of Giza
Great Wall of China
Taj Mahal
Serengeti Migration
Galapagos
Grand Canyon
Machu Picchu

The American Society of Civil Engineers compiled another list of wonders of the modern world:

Channel Tunnel
CN Tower
Empire State Building
Golden Gate Bridge
Itaipu Dam
Netherlands' Tidal Defences
Panama Canal

Natural wonders
Similar to the other lists of wonders, there is no consensus on a list of seven natural wonders of the world, as there has been debate over how large the list should be. One of the many lists was compiled by CNN:

Grand Canyon
Great Barrier Reef
Harbor of Rio de Janeiro
Mount Everest
Northern Lights
Paricutín volcano
Victoria Falls
