Because the palace was destroyed and rebuilt several times, it is difficult to determine its original layout and purpose.

The exact purpose of the Nazca Lines is not known, but they are believed to have been created for religious or ceremonial purposes, possibly as a form of communication with the gods. 

What makes the Nazca Lines fascinating is that they are best seen from the air. It is believed that the ancient Nazca people could not have created such precise designs without aerial observation. 

To this day, the Nazca lines are an enigma as they were created by a culture without a writing system, and it is not clear how the ancient Nazca people managed to create such precise designs without the use of modern technology.

Ancient Ruins

The Colosseum, also known as the Flavian Amphitheatre, was an oval-shaped arena built in Rome in the 1st century AD. It was used for a variety of public spectacles, including gladiator battles, animal hunts, mock sea battles, and public executions. The Colosseum had a complex system of underground tunnels and chambers that were used to stage these events. The underground area was called the hypogeum, which was a two-level subterranean network of corridors, staircases, and rooms, it was used to house gladiators, animals, prisoners, and other performers before they were brought up to the arena. The hypogeum also included mechanisms such as elevators, trapdoors, and pulleys that were used to create special effects during the shows.

Machu Picchu, Peru

Machu Picchu

Machu Picchu is a 15th-century Inca citadel that is located in the Andes Mountains of Peru. The site’s true purpose remains a mystery, and several theories have been proposed to explain its function.

Some theories about the purpose of this citadel have been put forward: for some, Machu Picchu would’ve been a royal estate, built as a summer residence for the Inca emperor Pachacuti. This theory is supported by the presence of many luxurious buildings, plazas, and terraces.

For others, Machu Picchu would’ve been a sacred religious site, used for religious ceremonies and rituals. This theory is supported by the presence of several religious structures, including the Temple of the Sun, the Intihuatana stone, and the Temple of the Three Windows.

But some researchers believe that Machu Picchu was a defensive fortress, built to protect the Inca empire from invaders. This theory is supported by the site’s strategic location and the presence of walls and towers.

And who knows? There is even the possibility that Machu Picchu was, in fact, a combination of all the above: a royal estate, a sacred religious site, and a defensive fortress all in one.


The Great Pyramids of Giza, Egypt

The Great Pyramids of Giza

Although many of the chambers and passageways have been explored and studied by scholars and researchers, this ancient funerary complex still holds many secrets.

Scholars still debate the exact years in which the pyramids were built, and little is known about how they came to be built.

The precise methods used to construct the pyramids, which were built with massive limestone blocks weighing up to 80 tons each, remain a mystery. Also, the hieroglyphs found in the pyramids are not fully translated and could potentially reveal more information about the pyramids’ purpose or the pharaohs that built them.
