Some ancient sites that have survived for centuries are troubled today
From Asia and Europe to the Americas and Africa, these sites provide history lessons
Ancient sites that have survived centuries, or even millennia, haven’t fared so well in the 21st century.
The destruction at Palmyra in Syria, the Buddhas at Bamiyan in Afghanistan and Nimrud’s ruins outside Mosul in Iraq show how precarious the future can be.
Here are 23 best ancient cities you can visit – destinations that offer glimpses into humanity’s past and the ingenuity that people brought to creating wonders without computers or heavy machinery.
Some are recognizable. Others are easily accessible but lesser known. All make for intriguing travel.
Angkor Wat, Cambodia
!["The Devata [goddesses] at Angkor Wat do all seem to be quite distinct from one another, leading several people to speculate they might be portraits of real people," says Carter. Case in point, this one-of-a-kind smiling lady, found near an entrance gate at Angkor Wat. You won't find another Apsara or Devata carving among the thousands at Angkor that shows her teeth says Cambodian guide Tong Hann.](https://media.cnn.com/api/v1/images/stellar/prod/150205133228-4-unesco-angkor-wat.jpg?q=w_2000,h_3000,x_0,y_0,c_fill/w_1280)
Exploring Angkor: Insider tips from the pros
In the 12th century, the Khmer took their vast understanding of the known universe and sought to recreate it in miniature.
The result was Angkor Wat, a sprawling city designed to impress with meticulously arranged moats and towers, and walls covered in astonishingly detailed bas reliefs of Hindu deities.
The ancient Khmer took a broad view of scenes worth preserving.
While many are celestial or holy in theme, other murals detail mundane acts like preparing supper.
Angkor Wat stretches over 500 acres within the Angkor Archeological Park, a large area covering more than 150 square miles.
The main temple receives packs of tourists, but many lesser-known temples offer a chance to wander through old Khmer capitals, which were built from the 9th century onwards.
Rome, Italy
Visiting a city as beloved as Rome comes with particular hazards: the crowds, the cheesy souvenirs, the young men in full gladiator regalia waiting to pose for selfies with tourists.
And yet there are few places like it.
Take the Colosseum – a nearly 2,000-year-old stadium in the middle of a modern city.
In the days of actual gladiators, 50,000 spectators would gather with the emperor for bloody contests to the death.
The Colosseum had the original retractable roof, a whizz-bang contraption called a velarium that used sail technology to rig canopies to shelter crowds from sun and rain.
And we’ve not even mentioned the Vatican, the catacombs or the Forum.
Istanbul, Turkey
Istanbul loves to depict itself as the city straddling two continents.
What’s most remarkable is the way the city straddles great periods of history that pile up and fold over themselves more naturally than anywhere else in the world.
Construction by successive empires from Byzantium to Constantinople to modern Turkey have bequeathed Istanbul an instantly recognizable skyline that merges elements from all those eras.
In the historic core around the iconic Hagia Sophia, the Byzantine-era Hippodrome circus sits a short stroll away from the Ottoman Empire’s Topkapi Palace, which houses artifacts including Moses’s staff.
Surrounding it all is a thriving modern city with top-notch dining, galleries and architecture that make Istanbul one of the world’s most important cultural centers.
Bagan, Myanmar
Long hidden from international view by Myanmar’s military government, the treasures of Bagan returned to the spotlight after political reforms began opening up the country.
Here, over 2,000 Buddhist temples fill a plain along the Irrawaddy River, creating an ethereal landscape.
The crowds remain far smaller and more adventurous than the tour groups that fill Angkor Wat or Machu Picchu.
Myanmar is still finding itself after decades of civil war and international isolation. The current crisis over the country’s treatment of the Rohingya Muslim minority is also attracting global criticism.
None of which makes this 11th-century temple city anything less than more magical.
The kingdom that reigned here was destroyed by earthquakes and Kublai Khan’s invaders, but the quiet temples retain a spiritual air that’s impossible to ignore.
Tikal, Guatemala
Hidden in the jungles of Guatemala, Tikal was a Mayan citadel that reflects more than 1,000 years of cultural achievements beginning from 600 BC.
Jaguars and pumas prowl the surrounding wilderness, but the palaces, temples and plazas within the site represent some of the earliest pinnacles of human achievement.
The stepped pyramids are icons of Mayan culture that rise above the canopy.
Equally impressive are the sporting courts, temples and palaces that ring the main plaza.
Most of the ancient causeways that link Tikal’s 3,000 structures have been cleared of vegetation, so visitors can now wander among the buildings much as the ancients did.
Cairo, Egypt
For first-time visitors, it’s a shock just how close the pyramids of Giza and the Great Sphinx are to Cairo’s chaotic streets.
With 22 million people, Cairo is one of the world’s biggest cities, built around one of humanity’s earliest urban centers.
Tombs at Giza date back 4,500 years, and the Egyptian Museum of Antiquities boasts an incredible collection from the Nile’s earliest inhabitants.
But the slightly less ancient parts of Cairo are also rich with cultural treasures.
The current city was founded more than 1,000 years ago and has one of the world’s oldest universities, a rich legacy of Islamic art, and Coptic treasures that are often overlooked.
Persopolis, Iran
34 incredibly beautiful reasons to visit Iran
Iran’s openness to Western tourism in recent years has helped Persepolis regain its allure for visitors, even if international relations have once more become strained.
The city was founded in 518 BC by Darius I, ruler of ancient Persia’s Achaemenian Empire, and grew in grandeur until Alexander the Great sacked it two centuries later.
Its most remarkable feature is an immense terrace of 125,000 square feet, partially carved out of Mount Kuh-e Rahmat (the Mountain of Mercy).
Rulers built ever more regal palaces, temples and halls around the terrace, complete with an underground sewage system and cisterns for fresh water.
Despite a series of protective walls, rising to 30 feet high, Alexander laid waste to Persepolis, whose ruins were only rediscovered in 1618.
Today, however, the city is one of the best examples of ancient architecture, especially for the slender columns that remain.
Kyoto, Japan
If Tokyo represents the part of Japan obsessed with technology and the future, Kyoto is the part that rakes sand in Zen gardens and performs graceful tea ceremonies.
That’s not entirely fair – Nintendo is based in Kyoto, just one part of the city’s thriving tech scene.
Perhaps closer to the truth is that as imperial Japan’s capital for more than 1,000 years, Kyoto has found a way to respectfully preserve its old traditions while eagerly embracing the new as well.
More than 1,000 Buddhist temples and Shinto shrines temper the frenetic pace of modern life. Sites such as Nijo Castle, which dates back to 1603, draw people from around the world.
Since the city was largely spared bombing during World War II, most are still in use.
Beijing, China
China has invested heavily in eye-popping modern architecture for its capital over the last two decades, but with a past that stretches more than 3,000 years, the city has a deep history providing a rich legacy of art, architecture and education.
Just visiting the city’s six UNESCO World Heritage sites, including the Forbidden City and the Temple of Heaven, could take a week.
That would barely allow even a casual glance at the treasures inside the city’s legion museums and galleries, much less the alleyways of the hutongs, old neighborhoods reinvented and sometimes rebuilt as a trendy center of the Beijing’s modern life.
Great Zimbabwe, Zimbabwe
From the 11th century, this kingdom in southeastern Zimbabwe grew into a trading empire that stretched through the African interior and across the Indian Ocean.
A royal complex grew on a hilltop, with drystone architecture creating a terraced palace with fruit trees, hidden chambers and stunning views over the king’s dominion.
Below, the towering walls of the Great Enclosure surround a conical tower that’s become a national symbol.
Overpopulation and deforestation caused the kingdom’s collapse around 1450 – historically bad timing as Europeans soon began arriving to find a weakened polity that was easier to subdue.
Great Zimbabwe remains a monumental reminder of Africa’s achievements before colonialism.
Timbuktu, Mali
Before the Sahara nearly swallowed the city and before French colonialists swept through, Timbuktu was one of the world’s most important centers of learning.
The city’s librarians guarded thousands of manuscripts, protecting them against the elements and violence.
Many of the manuscripts were evacuated to Mali’s capital Bamako during the last period of separatist violence, but the city’s unique mosques remain.
The three most important ones date as far back as the 14th century.
Their earthen architecture requires continuous maintenance, and caretakers today use the same techniques to preserve them as the original builders.
Machu Picchu, Peru
Nearly 8,000 feet high in the Andes, the Incan citadel of Machu Picchu retains an aura of mystery and majesty even as it welcomes thousands of tourists a day.
When the Spanish conquered Peru, Machu Picchu’s very existence was kept secret from them.
The vast complex was revealed to the outside world in 1911, and quickly became the emblem of Incan achievement.
Built more than 500 years ago with drystone construction, the city sits on the saddle between two peaks rising above tropical jungles.
Clouds swirl among the ruins, whose significance remains largely unknown.
Terraces and ramps skirt the mountains, and the buildings appear to reflect the Inca’s sophisticated grasp of astronomy – though archeologists are still seeking to understand exactly how.
Athens, Greece
Athens traces its origins back 5,000 years, but the modern city has found remarkable ways to coexist with its iconic ancient monuments.
Below the Acropolis, walkable neighborhood streets wind past cafes and shops.
Many brim with tourist tchotchkes, but with enough art galleries and good eating mixed among them even the most jaded traveler will be satisfied.
Much of the city’s social life centers around the monuments, turning the stunning ruins of classical Greece into casual backdrops of Athenians’ every day lives.
Petra, Jordan
This region between the Dead Sea and the Red Sea has been inhabited since the earliest days of humanity, but around 300 BC the rulers of the Nabatean Kingdom laid their claim to cultural greatness by carving magnificent buildings into red sandstone cliffs.
Gorges and canyons surround the ancient city, creating a maze of passages that helped keep it secret from Europeans for centuries.
