The world is home to a plethora of fascinating
ancient ruins, from crumbling cities to temples that have withstood the test of time. Many of these ancient societies were incredibly
innovative and forward thinking. Just take a look at their meticulous city
planning and incredible feats of engineering; some of which we are yet to fully understand. Some of the most captivating ancient ruins
are full of thousand-year-old mysteries that will boggle even the most curious of minds. Number 25. Ayutthaya. Founded around the year 1350, Ayutthaya is
a historical city that began as a Khmer military and trading post. It wasn’t long before this thriving trading
port became the ancient capital of Thailand. It held onto this title for four centuries
until it was burned down by Burmese invaders. As many of the temples and relics of the city
were crafted from wood, the large majority were destroyed. Only around 50 stone relics and temples survived
the fire and can still be seen today. Since renovations started in the 1970s, exploring
Ayutthaya’s mix of Siamese, Sri Lankan and Khmer architecture has become a popular day
trip from Bangkok. Number 24. Stonehenge. Dotted along the Salisbury Plain in Wiltshire,
England, Stonehenge is easily one of the most recognized ancient ruins in the world. Dating back over 5,000 years, these curious
stone rings are some of the oldest stone structures on the planet. Created out of sandstone, they are ensconced
in mystery. Who built them and why is still largely unknown. Two popular theories maintain that Stonehenge
was used as a site for religious rituals or otherwise to monitor the movements of the
sun and moon. As you only need two hours to explore the
ruins of Stonehenge, a day trip from London is often combined with a visit to Windsor
or Bath. Number 23. Mesa Verde. Deep in the American Southwest, you’ll find
Mesa Verde National Park with its fascinating collection of 600 ancient clifftop dwellings. The most famous of these dwellings is the
Cliff Palace, built into an enormous sandstone alcove that’s protected it from the elements
for over seven centuries. It’s the largest of its kind in North America
and unlike the rest of the dwellings that contained just a few rooms for residential
purposes, the palace had over 150 rooms and 23 sacred kivas. Having been lived in for close to a century,
these unusual cliff-side villages were suddenly abandoned in the 13th-century. Number 22. Sigiriya. Sigiriya is an ancient fortress carved into
a 200 meter vertical rock face in Sri Lanka. On top of what is now known as Lion Rock are
the fascinating remains of an ancient civilization, thought to be the capital of the kingdom of
Kassapa. In its heyday, it included a citadel, a mirror
wall with stunning colorful frescoes, and a gateway in the shape of a lion. After the king passed, the capital was abandoned
and it was used as a Buddhist monastery. While the climb to the top of Sigiriya is
certainly not for the faint-hearted, the views of the ramparts, terraced gardens and cave
shrines will be worth the effort. Number 21. Masada. The ancient fortress of Masada is possibly
one of the most impressive ruins on the planet. Perched on a cliff top overlooking the Judaean
Desert and the Dead Sea in Israel, the site is hauntingly beautiful. Dating back over thousands of years, it was
built as the palace of King Herod. It had modern creature comforts such as a
bathhouse and even private swimming pools. More famously, the enormous fortification
saw the last stand of the Jewish Revolt who chose death over a life of Roman slavery. Two pathways lead to the top and while grueling
in the beating sun, the views are worth it! Number 20. Hampi. The second-largest medieval city after Beijing,
Hampi was one of the wealthiest in India. Once the thriving epicenter of the Karnata
Empire with temples and imperial palaces, now only crumbling ruins remain. Founded in the 14th-century by two princes,
the former capital began as a simple riverside religious center. Highlights include the temple that served
as the royal family’s personal place of worship, the House of Victory, the Vitthala
Temple with its stone chariot and musical pillars, and the main temple with its carvings
of strange-looking sea creatures. Number 19. Pompeii. The eerie ruins of Pompeii can be found near
the Italian city of Naples. When the iconic Mount Vesuvius erupted in
79 AD, it destroyed the Roman city in waves of lava and took the lives of over 2,000 residents
along with it. The ancient city first discovered by accident
beneath the volcanic rock in the 1950s is remarkably well preserved. However, it wasn’t until two decades later
that it was properly excavated. You can walk down the streets of these ancient
Roman ruins and imagine the town as it was in its heyday. There are the remains of stone houses, temples,
bakeries, and even a brothel. Number 18. Tulum. An hours’ drive from Cancun, the Tulum ruins
are the remains of an ancient cliff top fortress built by the Mayans. Walled on three sides with the fourth open
to the Caribbean Sea, the views are simply incredible. Even though it dates back to 564 AD, Tulum
was at its prime during the 13th and 14th centuries. It was a powerful trading hub for jade, cotton,
and cacao beans. Apart from the El Castillo pyramid, the main
attraction, have a look at the beautiful mural inside the Temple of the Frescoes and go for
a swim at Tulum’s secret beach, surrounded by palm trees and sunbathing iguanas. Number 17. Ephesus. One of the most impressive Greek and Roman
ruins on Earth, the ancient city of Ephesus can be found in western Turkey. Dating back over 2,000 years, it was once
home to the famous Temple of Artemis. But what makes these ruins stand out is just
how immersive they are. Unlike many other protected archaeological
sites, you can touch, stand on and walk through every part of the city. Highlights include a series of ancient public
toilets, the Library of Celsus and Hadrian’s Temple. It is also home to the 25,000-seater Great
Theater of Ephesus, the largest outdoor theater in the ancient world. Number 16. Ellora Caves. The Ellora Caves are made up of a series of
caves, monasteries and temples carved into the side of a basalt cliff. Out of 100 caves, only 34 are open to the
public. Located in Maharashtra, India, Ellora dates
back to 600 AD and took Buddhist, Hindu and Jain monks over five centuries to craft. The highlight of the Ellora Caves is the Kailasa
Temple. Dedicated to Lord Shiva, it is the largest
monolithic sculpture in the world. Other worthy sights include the large preaching
Buddha in the Carpenter’s Cave, so-called because of the rock’s resemblance to polished
wood. Number 15. Terracotta Army. The Terracotta Warriors are an impressive
collection of thousands of life-sized soldiers and horses. Located in Xi’an, China, there are around
600 underground pits dating back to the 3rd-century BC. They were discovered by accident in the 1970s
when locals were digging for a well point. While many remain unexcavated, three of these
pits are open to the public and are enclosed within the Museum of the Terracotta Army. Apart from their sheer volume, what’s interesting
about these clay soldiers is that every single face is unique. They were hand-carved with individual features
and took around 40 years of craftsmanship in total. Number 14. Chichen Itza. One of the most famous archaeological sites
on Earth, Chichen Itza was once a thriving city on the Yucatan Peninsula. Built by the Mayans in 600 AD, it was abandoned
in 1221 when Mayapan became the region’s new capital. Highlights include the Temple of Kukulkan,
a giant stone pyramid with four stairways representing a compass and 365 steps for each
day of the year. It is best visited during the spring or fall
equinox when the sun creates a light show on the stairs of the pyramid. Other must-see sites include the Ball Court,
the Wall of Skulls, and the Sacred Cenote that was once a site of human sacrifice. Number 13. Acropolis. From its perch above the city of Athens, the
Acropolis topped by the Parthenon can be seen from any corner of the city. First built and inhabited by Pericles in the
5th-century BC, the Acropolis was eventually transformed into a city of temples. These ancient structures were crafted out
of bronze and marble, and some were even gold plated. Restorations are still ongoing so don’t
be surprised to find scaffolding still in place. Many of the original artefacts were relocated
to the Acropolis Museum so this is worth a visit while you’re here. Number 12. Bagan. The ancient city of Bagan is a captivating
temple town in Myanmar. Once the capital of a powerful kingdom during
the 11th and 13th centuries, it had over 10,000 temples, monasteries, shrines, pagodas, and
stupas in its zenith. In the years since, these sacred sites have
fallen into ruin as a result of Mongol invasions, neglect and natural disasters. Just 2,000 temple ruins remain and are scattered
over the horizon. While you can explore the Archaeological Zone
on foot, the sheer volume of temples is best appreciated from the air. A hot air balloon ride over Bagan is a worthy
addition to the bucket list! Number 11. Tikal. With its grey temple-tops protruding through
the lush canopy of the Guatemalan jungle, catching a glimpse of the ruins of Tikal is
something truly special. A popular day trip from Flores, these remote
ruins are dotted with pyramids, temples and palaces. One of the biggest archaeological sites in
Mesoamerica, Tikal was the largest and most powerful of the Mayan cities around 600 AD. Don’t miss the Temple of the Two Headed
Snake while you’re here. As one of the tallest pre-Columbian structures
in the Western Hemisphere, climbing to the top will treat you to incredible 360-degree
views of the rainforest and beyond. Number 10. Karnak. The Karnak Temple complex in Luxor, Egypt,
is impressive due to its sheer size. Covering an area that’s larger than most
ancient cities, it’s dotted with temples, obelisks, and shrines. It took over 2,000 years to build and each
Egyptian pharaoh left their own architectural mark. Walk through the Avenue of Sphinxes and discover
the Great Hypostyle Hall. This enormous room filled with towering pylons
and solid sandstone columns is one of the most famous and photographed attractions of
Ancient Egypt. While you’re here, stop to admire the Sacred
Lake and the nearby granite scarab. Number 9. Borobudur. Crafted out of an impressive two million blocks
of volcanic stone, Borobudur in Indonesia is the largest Buddhist temple in the world. Dating back to the 9th-century, it eventually
fell into ruin until it was discovered again in the 1800s. Since then, it has been restored to its former
glory and is particularly popular at sunrise. The Borobudur monument consists of six square
platforms topped by three circular platforms. A pathway of enlightenment leads from the
base of the pyramid up through the three levels of Buddhist cosmology, the world of forms,
and the world of formlessness. It’s decorated with over 2,000 reliefs and
500 Buddha statues, each one outlining a Buddhist teaching. Number 8. Teotihuacan. Located on the outskirts of modern-day Mexico
City, Teotihuacan is one of the most famous Aztec archaeological sites. But the Aztecs didn’t actually build it. Despite many theories, nobody is really sure
who did. However, the Aztecs did name it and make it
their own when they stumbled across the abandoned city. In its prime, it was the largest city in the
Western Hemisphere and home to a plethora of residential compounds and pyramids. Today, its two iconic pyramids, the Temple
of the Sun and the Temple of the Moon, are the major highlights. Stroll along the Avenue of the Dead and visit
the Citadel and the Temple of the Feathered Serpent. Number 7. Moai Statues. With the tallest weighing in over 80 tonnes,
the Moai Statues on Easter Island in Polynesia are iconic. In fact, you’ll probably recognize them
from a picture even if you hadn’t heard of them. These 800-plus statues, most of which face
away from the sea, were carved from volcanic ash by the Rapa Nui people somewhere between
400 and 1500 AD. Likely created using rudimentary basalt stone
picks, each of these enormous monolithic statues would have taken close to a year to complete. There are many theories as to why they were
built, including as a way to honor important clan ancestors and because of a believe it
would improve the soil. Number 6. Colosseum. One of the most iconic Roman ruins, the Colosseum
was an ancient gladiator arena. Unveiled in 80 AD, the 50,000-seater amphitheater
was used for staging various events. These included animal fights and blood-thirsty
gladiator battles where contestants would fight to the death. The architecture of the Colosseum is impressive
even by today’s standards. The outer walls are made up of three levels
of archways topped with Ionic, Doric and Corinthian columns. In its hey-day, they were decorated with marble
statues. The top level once supported an enormous awning
that sheltered spectators from the elements. Number 5. Great Wall of China. Spreading through 15 Chinese provinces and
autonomous regions, the Great Wall of China is the longest man-made structure in the world. It is made up of a series of separate sections
of walls and moats that were built over the course of six Chinese dynasties as a defense
from invaders. Now well over 2,000 years old, some parts
of the wall have fallen into ruin. Interestingly, for those who wanted to attempt
it, walking the entire length of the Great Wall of China would take approximately 18
months. Number 4. Petra. The Rose City of Petra is an ancient desert
town that was carved out of pink sandstone cliffs by nomads thousands of years ago. Located in Jordan, tucked between the Red
Sea and the Dead Sea, it’s hard to believe the city was once filled with green gardens,
palatial houses, and bustling markets. Instead, a walk or camel ride through the
ruins of Petra will reveal abandoned caves, temples, and tombs hidden within the city
walls. The two-story Treasury carved into the rock
face is one of the most beautiful landmarks in the old city. It’s worth viewing for the facade alone
but the interior with its Indiana-Jonesy royal tomb is worth a look. Number 3. Machu Picchu. A huge tick off the travel bucket list, Machu
Picchu is one of the most famous cities of the ancient Incan Empire. This historical fortress lies hidden in the
mountains of Peru. So well hidden in fact that it was never found
by Spanish invaders when they arrived in the 1500s. They were only accidentally discover in 1911
by an American explorer called Bingham. A wonder of advanced engineering, it’s estimated
that 60% of the construction was built underground, mainly for fortification and drainage. Today, these walled ruins can only be reached
by foot or by train. Don’t miss the Machu Picchu Museum for an
insider’s look into the Lost City of the Incas. Number 2. Angkor. Once the capital of the Khmer Empire between
the 9th and 15th centuries, Angkor was a thriving ancient metropolis. Today, the city is most famous for its Hindu
Angkor Wat Temple that claims the title as the largest religious shrine on Earth. It’s famously visited at sunrise when the
lighting over the temples is simply magical. But the Angkor Archaeological Park actually
includes many more fascinating landmarks aside from Angkor Wat. Over 1,000 temples lie scattered throughout
the forest, rice fields and farmlands. Highlights include the jungle-clad Tomb Raider
Temple with trees growing out of it’s ruins and the 12th-century Bayon Temple that marks
the historical center of the ancient city of Angkor Thom. Number 1. Giza. One of the most mysterious ancient sites on
Earth, the Pyramids of Giza in Cairo are truly fascinating. Created as enormous tombs for the pharaohs
of Ancient Egypt in the Fourth Dynasty, there’s plenty of speculation as to how they were
built. With such precise and immaculate detail, they’re
yet another remarkable feat of ancient Egyptian engineering. They were used as burial chambers and were
littered with treasure for the Pharaoh to use in the afterlife – something that attracted
many a grave robber over the years. Don’t forget to get a kissing photo with
the Sphinx – it’s pretty much mandatory.
