Being shattered by the death of his beloved wife, Shah Jahan decided to construct a domicile for the entombed. The grief of this Shah Jahan led to the formation of the glorious monument of Taj mahal. This ivory-white structure is thronged by its admirers from all over the world. Taj Mahal is an epitome of love, the beauty of which is more arresting during the sunrise and on a full moon night. Being built with the skillfulness of around 20000 artizans, Taj Mahal is the pinnacle spot in the city of Agra, India."),

This wall was constructed to protect the Chinese Empire from the assaults and invasions of the nomadic groups. The credit for the brawniness of this archeological grandeur goes to the robust stones, bricks, soil, wood, and other materials used for its construction. This monument symbolizes the strength and dexterity of the artisans in the bygone times. Being swarmed by its admirers from every nook of the world, the Great Wall of China stands tall to inspire the generations to come."),

Being an embodiment of the Brazilian Christianity, this wonder of the world is the most groovy structure in Rio de Janerio, Brazil. The reason behind the unconventional strength of this structure is the adoption of reinforced concrete and soapstone for its construction. You would be astounded to know that this stupendous edifice was engineered in pieces and then taken on the top of a mountain for compilation. The statue of Jesus Christ embracing the entire world is venerated not only by the Christians, but the people belonging to other religions as well."),

"The center of the Rome accommodates the spectacular structure of the largest amphitheatre in the world, a.k.a., The Colosseum. It depicts the finesse of the engineering works during the Roman Empire. This otherworldly edifice took 9 years to get completed. If we think of mastering a structure of such massive expanse with all the contemporary methods, wistfully, we would fail to meet the deadlines confronted by the adept architects of those times. This amphitheatre witnessed a plethora of capital punishments and battles, that led to the death of around 400,000 people inside this structure. This structure has been a beholder of several events, shows, contests, and much more. And Mr. Moviebuff, you would be amazed to know that the climax scene of the epic movie Gladiator was shot nowhere else than The Colosseum."),

The preeminent structures of the Machu Picchu comprise of the Inti Watana, The Temple of the Sun, and the Room of the Three Windows.
