The Pamana Canal
he Panama Canal is a 48 mile (77 kilometers) long ship canal that connects the Atlantic and the Pacific Oceans. The canal was built from 1904 to 1914 and it was one of the most difficult engineering projects ever pioneered. The opening of the canal had a tremendous impact upon shipping between the two oceans, since all the boats en route from one ocean to the other did not have to route around the notorious Cape Horn anymore, America’s southernmost point. -

Preparations also included the creation of four diversion tunnels, in order to redirect the Colorado River from -
The Colosseum
This is the largest amphitheater ever built in the Roman Empire and definitely one of the greatest achievements of Roman engineering. It only took eight years to finish this amazing structure that continues to stand as Rome’s most prestigious symbol for almost 2,000 years now.

The Channel Tunnel
The Channel Tunnel is a 31.4 miles (50.5 kilometers) undersea tunnel that connects Folkestone, in the United Kingdom with Coquelles, in Northern France. The tunnel reaches up to 250 ft (75 meters) deep, and seven years after its opening it still possesses the largest underwater portion of any tunnel in the world: 23.5 miles (37.9 kilometers). It is now used by high-speed Eurostar passenger trains, Eurotunnel Shuttle vehicle transport and freight trains. -
Kansai Airport
The Kansai International Airport is the first airport ever to be built on a 100% man-created island. It was built as a solution to the old airport, which was located in a highly-populated area, leaving no room for further expansions. It took 3 years and ten thousand workers. It opened in 1994 September 4. -
