10 ENGINEERING MARVELS

We live in modern times were we have built structures which touches the sky. But one has to wonder how humans who live more than two to three thousand years ago managed to build such edifice. Building structures which modern day engineers have no idea how they were built. Let us explore such human achievements of the past.

  1. The Great Wall of China

The Great Wall of China is the only manmade object which can be seen from space and it was built especially famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains. Since then, the Great Wall has on and off been rebuilt, maintained, and enhanced; the majority of the existing wall is from the Ming Dynasty

  1. Rome Colosseum 

Construction began under the emperor Vespasian in 70 AD, and was completed in 80 AD under his successor and heir Titus. It is the world’s biggest amphitheater. It is considered one of the greatest works of Roman architecture and engineering but within the walls it has a sad history of violence and death.

  1. Angkor wat

This place of worship still remains the biggest temple complex in the world. to was built in the 12 century by the great Khmer King Suryavarman II for lord Vishnu. Angkor itself means city of temples. Later one this Hindu temple became a center for Buddhism. This is a remarkable piece of engineering and planning.

  1. Taj Mahal

One of the most beautiful pieces of architecture ever and it was built by the Mughal emperor Shah Jahan in memory of his third wife, Mumtaz Mahal but it also has a sad history because this so called building of eternal love for Shah Jahan for his wife was built over the misery of the common people. It is one of the most beautiful structures in the world but in the words of Rabindranath Tagore “The Taj Mahal rises above the banks of the river like a solitary tear suspended on the cheek of time”.

  1. Pyramids

Built more than 4000 years go by the Egyptians this structure has baffled engineers for centuries. Theses massive structures were built as the final resting place for the kings or known as the Pharaohs. Over the years it has been damaged due to war. But still this building as stood the test of time.

  1. Rome Pantheon 

This building was built nearly 2000 years ago by the Roman Emperor Hadrian, but it was originally commissioned by Marcus Agrippa a man known for his love of engineering and Architecture. This building is unique because of a rectangular vestibule links the porch to the rotunda, which is under a coffered concrete dome, with a central opening (oculus) to the sky. Even after almost two thousand years after it was constructed, the Pantheon’s dome is still the world’s largest unreinforced concrete dome.

  1. Sanchi Stupa

This structure was built more than 200 years ago by Ashoka the Great. He was a man who gave up violence and perhaps is the first king in the world who said that all human being have rights.  The Great Stupa at Sanchi is perhaps the oldest stone structure and its nucleus was a simple hemispherical brick structure built over the relics of the Buddha. It was crowned by the chatra, a parasol-like structure symbolising high rank, which was intended to honour and shelter the relics.

  1. Teotihuacan

Teotihuacan also written Teotihuacán in Spanish is pre-Columbian Mesoamerican city located in the Valley of Mexico, 48 km northeast of modern-day Mexico City. It’s been said by experts that it was built over 2000 years ago and the Architecture is breath taking. The entire area covered is equivalent to any average size modern city.

  1. Machu Picchu

Built at hight of nearly 8000 feet, this Architecture wonder has still left many Architects and modern engineers completely bamboozled because they still have not figured out how the Inca managed to move such heavy rocks to such heights. This one still is a mystery

  1. El Mirador

This place remained unknown until recently and it has generated a huge interest in the scientific community. El Mirador flourished from about the 6th century BCE, reaching its height from the 3rd century BCE to the 1st century CE. It has been said by experts that there was a time when over one hundred thousand people lived there.
