From ruins to revelation: The remarkable rediscovery of six ancient cities

The history of human civilization is full of mysteries and surprises. Some of the most fascinating are the ancient cities that were once thriving centers of culture, trade, and power, but were later abandoned, forgotten, or hidden by natural disasters, wars, or time. These cities offer a glimpse into the past and reveal the achievements and challenges of our ancestors. Here are six ancient cities that were rediscovered by modern explorers and archaeologists.

Upano was an ancient city that was hidden in the Amazon rainforest of Ecuador. It was recently discovered by a team of archaeologists using LiDAR, a remote sensing technology that uses lasers to map the terrain. The city dates back to between 3,000 and 1,500 years ago, and consists of more than 6,000 earthen platforms that were used as the foundations for wooden buildings. The city also had a sophisticated network of roads and canals that connected the different settlements. It is one of the oldest and largest pre-Columbian cities ever found in the Amazon, and challenges the idea that the region was only inhabited by small and nomadic groups.

Ebla was a powerful city-state that dominated the region of northern Syria and parts of Mesopotamia in the third millennium BCE. It had a complex political and economic system, a rich cultural and religious life, and a vast library of cuneiform tablets that contained records of laws, treaties, trade, literature, and history. Ebla was destroyed by the Akkadians around 2250 BCE, and then rebuilt and destroyed again by the Hittites around 1600 BCE. The city was eventually abandoned and its location was lost until 1964, when an Italian archaeologist, Paolo Matthiae, started excavating the site of Tell Mardikh and discovered the remains of Ebla and its archive.

Pompeii was a prosperous and lively Roman city that was located near the Bay of Naples in Italy. It had a population of about 20,000 people, who enjoyed a variety of amenities, such as baths, theaters, temples, markets, and villas. Pompeii was also a victim of one of the most devastating natural disasters in history, when the nearby volcano Mount Vesuvius erupted in 79 CE and buried the city under a thick layer of ash and pumice. The city was preserved by the volcanic material, which created a time capsule of the Roman life and culture. Pompeii was rediscovered in the 18th century, and since then has been extensively excavated and visited by millions of tourists.

Mohenjo-daro was one of the largest cities of the ancient Indus Valley Civilization, which flourished in South Asia from the 3rd to the 2nd millennium BCE. It was built around 2500 BCE and had a population of about 40,000 people, who enjoyed a variety of amenities, such as baths, theaters, temples, markets, and villas. Mohenjo-daro was also a victim of one of the most devastating natural disasters in history, when the nearby river Indus flooded and buried the city under a thick layer of mud. The city was preserved by the mud, which created a time capsule of the Indus culture and life. Mohenjo-daro was rediscovered in the 1920s, and since then has been extensively excavated and studied by archaeologists and historians.

Palenque was one of the most important and beautiful cities of the Maya civilization, which flourished in Mesoamerica from the 3rd to the 9th century CE. Palenque was known for its impressive architecture, art, and astronomy, and for being the home of the famous ruler Pakal, who was buried in a magnificent tomb inside the Temple of the Inscriptions. Palenque was abandoned around the 10th century CE, and was gradually covered by the dense jungle. It was rediscovered by Spanish explorers in the 18th century, and later studied by archaeologists and epigraphers, who deciphered the Maya hieroglyphs and revealed the history and secrets of the city.

Petra was the capital of the Nabataean kingdom, which ruled over the lands of southern Jordan and northern Arabia from the 4th century BCE to the 1st century CE. Petra was a remarkable city that was carved out of the red sandstone cliffs, and featured elaborate tombs, temples, palaces, and monuments. Petra was also a strategic and wealthy city that controlled the trade routes between the Mediterranean, Arabia, and India, and was famous for its water management system, which included dams, canals, and cisterns. Petra was conquered by the Romans in 106 CE, and later declined due to earthquakes and changing trade patterns. The city was abandoned and forgotten by the 7th century CE, and was only rediscovered in 1812 by a Swiss explorer, Johann Ludwig Burckhardt, who disguised himself as an Arab traveler and entered the hidden city.
