From the Great Pyramid built almost 3000 years ago with over 2million stones weighing 2.5 tons each to the Palm Islands in Dubai, built of islands that had to be constructed from rock and sandstone, to stepping out onto an oval glass ring above the Grand Canyon.

These are just a couple of amazing constructions found around the world and here are some of the greatest feats of engineering that we think are worth a mention.

The Great Wall of China is 8,850 kilometers long (5,500 miles) and was constructed over a period of 2,000 years.

Construction began in 475 BC, to protect China from the invading Huns.

During the Ming dynasty, between 1368 and 1644 A.D, it was given a makeover, with the addition of watchtowers, battlements and cannons some of which stand 980 meters above sea level.

The mortar used to bind the stones of the wall is made from rice flour.

Originally built to protect the northern territories of China from invasions, the Great Wall has been rebuilt and maintained for more than 16 centuries.

The wall stretches for 5,500 miles (8,851 km), including some natural defensive barriers such as hills and rivers.

Unlike many other fortifications at that time, bricks and stone were used in the construction of the Great Wall, instead of rammed earth.

In the Juyongguan pass, the wall reaches 25.6 feet (7.8 meters) in height and 16.4 feet (5 meters) in width.

In some other areas, the wall climbs steep slopes and is completed by watchtowers built up to 3,215 feet (980 meters)above the sea level.

It is estimated that while building this amazing fortification, more than 1 million workers lost their lives.

Completion date: 204 BC.

Explorers weldon work. Lemme sit right here as I enjoy the flight.

The Trans-Siberian Railroad connects Moscow and Eastern Russia with Japan, China and Mongolia.

Northern Siberia isn't the easiest landscape to cross, which is what makes the 8,851km(5,500 mile)Trans-Siberian railway so impressive.

Engineers had to design a railway that was capable of operating in temperatures of minus 20 degrees Celsius.

The railway travels through eight time zones, 87 towns and cities and crosses 16 major rivers.

Some 90,000 people helped construct the railway, which took 10 years to build, pretty impressive considering the tools at workers' disposal were shovels, picks and wheelbarrows.

Completion date: 1904.

Nice post but can you explain more on the quoted. Thanks.

Burj Khalifa, Dubai, UAE.

The Burj Khalifa has a height of 828 meters and is both the tallest building in the world and the tallest free-standing structure in the world.

Engineers faced multiple challenges, including the strong winds that batter the tower.

Because of this, over 40 wind tunnel tests were conducted, not just to determine how the wind would affect the building but also to test the cranes used to construct it.

Cost: $1.5Billion.

Completion date: January 4, 2010.

The Palm islands comprise approximately 100 million cubic meters of rock and sand.

In total, 210 million cubic meters of rock, sand and limestone were reclaimed (through dredging) to create the islands, with 10 million cubic meters of rockused in the outer ring alone.

The rocks used for both islands were transported from 16 quarries throughout the UAE and the materials used are enough to build a wall that could circle the world three times.

Completion date: September 24, 2008.

Was it not the same track that end at vladivostok
in far east Russia. The longest railtrack in the world connecting two continents.

Great Pyramid of Giza, Egypt.

The Great Pyramid was the tallest man-made structure in the world for more than 3,800 years.

The builders responsible for the Great Pyramid of Giza would have needed more than a few tea breaks to keep them motivated.

The pyramid consists of 2.3 million stone blocks.

The largest ones, found in the King's chamber, weigh between 25 and 80 tons and were transported to the site from Aswan, 800 kilometers away.

In total, 5.5 million tons of limestone, 8,000 tons of granite and 500,000 tons of mortar were used.


How did they cut the stone into the perfect shapes, how were the stones transported from over 800km, and how were the stones lifted to that height and arranged perfectly(139m).

No caterpillars, no bulldozers, no excavators, no rock saw, drilling equipments, and no cranes or lifting equipments/machineries.

Experts have never worked out these questions, how the blocks were moved into place.

Completion date: 2504 BC.





I just wish the sun, moon, and stars are CCTVs.

We would just hack into them and play back to 5000 years.

Because the sun will be shining up in the sky while the construction was going on and the Moon/stars up in the sky as they work through the dark of the night.

let me pitch my tent here cause I will be sailing to the home land...


Very educative from the exploer himself.

Educative. Hope to see "the longest suspension bridge on earth"

Panama Canal, Panama.


More than 4.5 million cubic yards of concrete were used in the construction of this canal's locks and dams.

The Panama Canal is a 77-kilometer (47-mile) long waterway that connects the Atlantic and Pacific Oceans.

The ingenious network of dams and locks linking two oceans took more than 75,000 workers more than ten years to build.

The earth and rubble excavated to make way for it was enough to bury Manhattan to a depth of four meters.

A series of locks allows ships to pass through the water; each of the moveable lock doors weighs 750 tons and each of the locks fills with 52 million gallons of water to accommodate the 15,000 ships that use the canal every year.

The first ship sailed through in 1914. Today ships line up on each side, waiting their turn to enter the canal, which operates around the clock.

Completion date:January 7, 1914.

This remains one of the mysteries of the Ancient world. Billyonaire came up with a theory that it was contracted by gods or something

Africa ought to have some engineering feats...

Taipei 101, Taipei.


Taipei 101 was the first building in the world to break through 500 meters.

Upon its completion, the tower claimed several records: it had the world's fastest elevator, was the world's tallest building and was the world's tallest structure, thanks to its spire.

Eight "mega-columns" make the building especially earthquake resistant.

Completion date:December 31, 2004.

Yeaaaaaa, I will upload a picture of me on the Great wall. Just wait

Explorer carry go!

Nice one @Explorers.

The Burj Khalifa is simply awesome!

A beg help me with that Billyonaire's thread about the pyramid

I de follow the thread like tail... very educative

London Underground, London.


Aldgate Station, on the Circle, Hammersmith and City and Metropolitan Lines, is built on a huge plague pit, where more than 1,000 bodies were buried.

The London Underground celebrated its 153th birthday this year.

The entire network has a length of 402 kilometers (249 miles) and more than 1 billion journeys are made every year.

When it opened in 1863, it was the world's first underground railway and the trains, which traveled between Paddington and Farringdon, were gas-lit wooden carriages pulled by steam locomotives.

Completion date: January 10, 1863.

Kansai International Airport, Osaka, Japan.



Kansai International Airport was the first airport to be built on an artificial island.

Osaka is one of Japan's most crowded cities, so when a new airport was called for, engineers came up with a novel solution , a man-made island.

Construction of the island, which measures four kilometers (2.5 miles) by 2.5 kilometers (1.6 miles) took three years.

Some 10,000 workers and 80 ships were used to excavate 21 million cubic meters of landfill and the island's construction became the world's most expensive civil engineering project, with a total cost of$20 billion.

Completion date: 1994.

Is this fiction or non-fiction or some "over-exaggeratted stuff? Circle the world 3x?
