Se7en modern wonders of the worldThe ancient Greek spoke of the Seven Wonders of the World. Recently, some engineers came up with the list of the Seven Wonders of our modern World:
The Panama Canal, began in the 1880s, wasn’t finished until 1914. It joins the Atlantic and Pacific oceans. Engineers describe the canal as a victory of humans over geography. Workers dug huge amounts of land and tamed rivers.
For 40 years after it was completed in 1931, the Empire State Building, in NY City, was the tallest building in the world. Amazingly this 102-storey building was constructed in just 410 days.
The Netherland North Sea Protection Works is another victory over geography. The Netherlands, which is below sea level, was often flooded by the North Sea and by rivers. Then, between 1927 and 1932, a dam was built to shut out the sea. 20 years later, dams and canals were built to control the rivers.
The Golden Gate Bridge completed in 1937 was also a challenge for workers: San Francisco Bay has very strong winds and rough waves. The Golden Gate is still the world’s tallest bridge. It has enough steel to wrap around the world three times.
At 1815 feet, the CN tower, in Toronto, Canada, is one of the world’s tallest free-standing buildings. Completed in 1976, the tower is used for TV and Radio broadcasting.
The Itaipu Dam, completed in 1984, goes across the Parana River at the Brazil-Paraguay border. It is the world’s largest hydroelectric plant.
Completed in 1994, the Channel Tunnel joins France and England. The “channel” is remarkable convenience: cars, buses, and trucks are all carried through the tunnel by train.
