From temples and monuments to cities and settlements, these magnificent ruins help unlock the mysteries of humanity’s shared past.
Empires rise and fall, but even when the last people of any culture have gone, hints of their history remain. The many ancient ruins found around the world stand as reminders of these lost civilizations, monuments to our ancestors that are often as mysterious as they are illuminating.
When these ruins are rediscovered, they have the ability to fundamentally rewrite our understanding of history. Through archaeological expeditions, researchers have learned of lost cities, forgotten religions, and even entire civilizations that had previously gone unrecognized. From Stonehenge to Machu Picchu, the structures crafted by ancient humans have created lasting legacies that live on in the place of the people who built them.

The earliest fortifications of the Great Wall of China date back to the seventh century B.C.E. However, the most famous stretches of the Great Wall were constructed during the Ming dynasty, between 1368 and 1644.
Now a world-famous tourist destination, the structure spans over 13,000 miles in total, and it once served as both a military defense strategy and a means of controlling trade along the Silk Road.

The ancient Pisidian city of Termessos, in Turkey’s Taurus Mountains.
Built on rugged, steep terrain more than 3,000 feet above sea level, it was naturally fortified and virtually impenetrable. Even Alexander the Great was unable to invade the city due to these natural defenses.
Despite this, Termessos was eventually abandoned around the 5th century. Damage from earthquakes and the city’s remote location made it extremely difficult to get a reliably consistent supply of water, and it’s believed that water shortages played a big role in its abandonment.

Stonehenge, One Of The Most Mysterious Ancient Ruins In The World
Standing on the Salisbury Plain in Wiltshire, England, Stonehenge remains one of the most enigmatic prehistoric monuments on Earth. For centuries, the towering stone circle has captivated visitors and archaeologists, while its mysterious origins continue to fuel speculation and debate.
From various studies, researchers have made a few keen observations about Stonehenge. It is now known that the monument’s construction spanned about 1,500 years, beginning during the Neolithic period around 3100 B.C.E., with the most recognizable stone circle erected sometime between 2600 and 2400 B.C.E. — an impressive feat, given that some of the massive sarsen stones weigh about 25 tons. Most of these seem to have been transported from the Marlborough Downs, located about 18 miles away.
Even more remarkable, the smaller bluestones originated from the Preseli Hills in Wales, some 150 miles away. Transporting these stones over such a long distance would have required sophisticated planning among ancient British societies. However, it’s still unclear who exactly built the structure.
Wikimedia CommonsStonehenge, the mysterious ancient ruins on Salisbury Plain.
The original purpose of transporting and erecting the stones is also a mystery. Archaeological evidence suggests that Stonehenge served multiple purposes throughout its long history, functioning as a burial ground for cremated remains for at least part of the time.
Stonehenge’s precise astronomical alignments, particularly during the summer and winter solstice, suggest that it could have also operated as a sophisticated calendar and observatory, helping ancient people track seasonal changes that were crucial for agriculture. Ground-penetrating radar has also uncovered a vast landscape of buried monuments surrounding the stone circle, including a timber building, burial mounds, and settlement sites.
Today, Stonehenge stands as a UNESCO World Heritage Site, attracting more than one million visitors every year. Unlike some other ancient ruins, though, the known story of Stonehenge is relatively peaceful and calm so far. Unfortunately, the same can’t be said for the fate of Pompeii.
The Destruction Of Pompeii After The Eruption Of Mount Vesuvius
Wikimedia CommonsThe House of the Faun at the ancient ruins of Pompeii.
In 79 C.E., the bustling Roman city of Pompeii fell victim to a devastating volcanic force. Mount Vesuvius suddenly erupted, and in less than 24 hours, the thriving commercial hub was buried beneath volcanic ash and pumice, eerily preserving the tragic fate of its residents for eternity.
Prior to the catastrophe, Pompeii had been a prosperous city of around 20,000 people. First settled in the 8th century B.C.E., it had evolved from a small agricultural settlement to a sophisticated urban center with paved streets, elaborate villas, public baths, and a massive amphitheater that could seat up to 20,000 spectators. Pompeii’s location was highly strategic, given the proximity to the Bay of Naples, which helped transform the city into a vital trading port where merchants sold products like wine, olive oil, and garum — a fish sauce that was beloved in ancient Rome.
All of this was suddenly gone, however, once Vesuvius erupted. A towering surge from the volcano shot as high as 20 miles into the sky, and as the volcanic debris rained down, most of Pompeii’s citizens fled in panic. Tragically, many were trapped by the rapidly accumulating ash. The pyroclastic flow that followed killed those who remained, instantly preserving eerie details of their final moments in hardened volcanic material.
Pompeii remained largely hidden beneath the volcanic ash for centuries, until accidental discoveries in the 16th century eventually led to systematic excavations, which started in 1748. As the excavations became more organized, historians were eventually able to create plaster casts of victims, which were made by pouring plaster into the air pockets in the debris that contained human bones, which were left behind after the victims’ bodies decomposed. Today, the plaster casts on display at the site offer a morbid yet fascinating glimpse into the final moments of the people of Pompeii.
Archaeologists continue to study the ancient ruins of Pompeii to this day, with new discoveries being made with surprising regularity. In this aspect, though, Pompeii is not wholly unique. Another archaeological site known as Angkor Wat has also proven to be a trove of archaeological treasures.
Angkor Wat, The Marvelous Crown Jewel Of The Khmer Empire
Tommy Trenchard/Alamy Stock PhotoRhesus monkeys at the ancient ruins of the temple complex of Angkor Wat in Cambodia.
The temple complex of Angkor Wat in Cambodia is the world’s largest religious structure and a testament to the architectural fortitude of the Khmer Empire. The name translates to “Temple City,” and construction began on it in the 12th century under the orders of King Suryavarman II.
It was originally intended to be a Hindu temple dedicated to Vishnu. Construction took around 30 years and wound up spanning over 400 acres. The overall layout of Angkor Wat was meant to represent Mount Meru, the sacred mountain and center of the universe in Hindu cosmology. The temple’s five central towers symbolized the mountain’s peaks, while the surrounding moats represented the cosmic ocean.
The project reportedly required 300,000 workers and 6,000 elephants to complete. Its builders sourced massive sandstone blocks from a nearby mountain for the project, transporting the materials via canals and rivers. The temple’s intricate bas-reliefs ended up stretching nearly half a mile and depicting a number of epic Hindu narratives, including the “Churning of the Ocean of Milk” and scenes from Ramayana and Mahabharata.
Angkor Wat evolved over time as well. During the 13th century, as Buddhism became more prominent in the region, the temple transformed from a Hindu temple to a Buddhist shrine. The monks who resided there added Buddhist statues and imagery, while also preserving some original Hindu artwork, creating a unique religious synthesis that can still be seen today.
As the Khmer Empire declined in the 15th century, Angkor Wat was gradually abandoned. Over the years, the jungle reclaimed much of the complex, though Buddhist monks continued to maintain parts of the temple.
The site was then reintroduced to the Western world after the French explorer Henri Mouhot came across it around 1860, and numerous archaeological excavations at the site since have yielded a wealth of artifacts that shed light on the history of the Khmer Empire. 3D mapping and digital reconstructions have also helped archaeologists understand the site better, while protecting it from environmental challenges and pressures of tourism.
Angkor Wat is considered so historically significant that it’s even the central symbol on the Cambodian flag. It is perhaps one of the greatest examples of why ancient ruins are so captivating and significant, even hundreds — sometimes thousands — of years after their heyday.
