The world is home to incredible historical treasures that have endured for centuries, even millennia. Many of these sites were hidden from humanity for ages before being rediscovered. Unfortunately, due to urbanization, natural calamities, and environmental damage, these iconic landmarks face the threat of disappearing again by the end of this century.
10. Glacier National Park
Approximately 10,000 years ago, Montana’s Glacier National Park was buried under ice as deep as 1.6 kilometers (1 mile). At its establishment in 1910, the park boasted about 150 glaciers. Today, only 25 remain, and experts predict they could vanish entirely by 2030.
Grinnell Glacier, the centerpiece of the National Park, has seen over 90% of its ice vanish in the last hundred years. While global warming is the primary culprit, the park is suffering disproportionately: temperatures here have risen 1.8 times faster than the global average.
The threat extends beyond the glaciers. The icy streams fed by these massive ice formations sustain the park’s delicate ecosystem, home to wolves, elk herds, and one of the largest grizzly bear populations in the lower United States. If the glaciers vanish, not only will a relic of the Ice Age be lost, but numerous species will face the collapse of their natural habitat.
9. The Valley Of Kings
The burial sites of Egypt’s legendary pharaohs, including Ramses II and the young Tutankhamun, have captivated imaginations for centuries. Sadly, they have also attracted countless treasure seekers, many of whom were nothing more than looters and thieves.
Today, the Valley of Kings faces a new danger, not from treasure hunters but from the thousands of tourists who visit each year. Fungus has started to spread uncontrollably around the tombs, a problem scientists attribute to inadequate ventilation and the breath of countless visitors. Egypt’s antiquities authority warns that the tombs could be lost within 150 years if no action is taken.
The intricate carvings and paintings within the tombs are already fading. To combat this, authorities have limited the number of visitors and permanently closed some tombs. These measures, combined with improved ventilation systems, aim to preserve these ancient wonders for future generations.
8. Seychelles
The Seychelles, a cluster of roughly 115 islands near Madagascar, remains relatively unknown to many. These islands were untouched by humans until the British East India Company stumbled upon them in the 1600s. Later, they became a refuge for pirates. Now, they are renowned as a prime location to spot whale sharks, the ocean’s largest fish. The Seychelles also boasts some of the earliest scientific documentation on these majestic creatures, which are now rigorously protected.
The Seychelles, however, could vanish beneath the waves within 50 years, primarily due to the degradation of their coral reefs. These islands have experienced some of the most severe coral bleaching events globally. Rising ocean temperatures kill the coral, turning it into a ghostly white skeleton, which devastates marine ecosystems and leaves the islands exposed to catastrophic storms like hurricanes.
7. Olympia
Ancient Greece often brings to mind images of Greek mythology, Spartan warriors, or the Olympic Games. While many know the Olympics originated in Greece, few are aware of the specific city where they began.
Over the centuries, Olympia has been home to various cults honoring different deities, from Kronos, the Titan king, to Aphrodite, the goddess of love and beauty. Eventually, one cult took full control of the city, dedicating it to Zeus, the king of the Olympian gods. Nearly every aspect of Olympia was built to honor him, including a towering 13-meter (42 ft) gold-and-ivory statue (now lost to history) and the Olympic Games. Even today, the Olympic flame is lit in this ancient city before being carried to the host country of the games.
Ironically, the birthplace of the Olympic Games is now under threat from fire. In 2007, arsonists ignited wildfires that raged across the region, claiming over 60 lives. Firefighters narrowly prevented the flames from engulfing the historic site, which was just a hillside away from destruction. Due to global warming, such fires have become more frequent and intense, putting the ancient site at risk of being reduced to ashes and nullifying preservation efforts.
6. The Chan Chan Archaeological Zone
Chan Chan, recognized as the largest pre-Columbian city ever discovered and the biggest adobe city in history, spans approximately 20 kilometers (12 miles) in Peru. It was originally home to the Chimu civilization, who organized the city into nine independent citadels.
Anthropologists have hailed Chan Chan as the “first true engineering society in the New World.” Their innovations, including a city-wide irrigation system and an ambitious canal project aimed at connecting to the Chicama River 80 kilometers (50 miles) north, were unparalleled in Europe at the time. The city thrived for over six centuries before falling to the Incan Empire.
Today, this archaeological treasure faces threats not only from looters but also from the destructive storms triggered by El Nino. Adding to the peril, frequent and powerful earthquakes risk reducing the ancient city to rubble.
5. The Galapagos Islands
Familiar to anyone who has studied high school biology, the Galapagos Islands inspired Charles Darwin’s theory of evolution. These remote islands are home to nearly 9,000 species, many of which are found nowhere else on Earth. Sadly, the unique wildlife that defines the Galapagos is now under serious threat.
With the rise in immigrant workers and tourists—the latter increasing by over 12 percent annually—invasive species have also proliferated. Goats and pigs consume the resources native species depend on, while predators like rats prey on the vulnerable. For millennia, the islands had no predators, and evolution moves too slowly for many of these unique creatures to adapt in time.
4. The Chersonesos Archaeological Site
Located in modern-day Ukraine, southwest of the Crimean Peninsula, Chersonesos is an ancient Greek settlement established between 300 and 200 B.C. Despite being one of the few democratic societies of its time, historical accounts reveal it was frequently at war with the Scythians and the Roman Empire, eventually falling to the latter.
By the fifth century, many Greek structures and temples were demolished as Christianity rose to prominence. Even after becoming part of the Byzantine Empire, the city faced further devastation when nomadic tribes raided and burned it centuries later.
The Soviet Union uncovered the site after annexing Crimea in the 1800s. It was meticulously preserved and restored, becoming a key location for Russian historians and archaeologists. Today, it faces threats from both nature and human activity, including coastal erosion, pollution, and urban expansion.
3. Lamu, Kenya
Designated a World Heritage Site in 2001, Lamu dates back to the 14th century. As one of the earliest Swahili settlements on Africa’s east coast, it remains inhabited today. At its peak, Lamu was a thriving hub of art, politics, and literature. It later served as a strategic location for both Germany and Britain before gaining independence with Kenya in the 1960s.
Despite centuries of bustling activity, Lamu is now seeing a decline in residents and visitors. In 2011, travel to Lamu was restricted following kidnappings by the terrorist group Al Shabaab, who cite retaliation for seized Muslim territories as their motive. Recent violent attacks have further destabilized the city, making it nearly impossible to preserve landmarks like Lamu Fort.
2. Hisham’s Palace
Hisham’s Palace lay buried beneath the sand from A.D. 747 until Palestinian archaeologist D.C. Baramki began excavations in 1934. Unfortunately, experts warn that the site could disappear within the next century.
The true purpose of Hisham’s Palace remains a mystery. When it was buried, it also disappeared from historical records. The only clue is a piece of pottery inscribed with the name “Hisham.” Robert W. Hamilton, Baramki’s colleague, suggests this indicates the palace belonged to Al-Walid II’s heir. What is certain is that it was constructed in the early 8th century and destroyed by a powerful earthquake.
Sadly, the palace’s secrets may remain hidden forever. It faces threats from the rapid growth of nearby Jericho and is highly susceptible to natural decay after centuries underground. The sand seems to be reclaiming it once more.
1. Intramuros
This district in Manila, the Philippines’ second-largest city, translates to “within the walls.” The name is fitting, as the same walls erected in the 16th century still stand today, despite significant damage over the centuries. It served as the city’s original capital during Spanish colonial rule.
During World War II, the Imperial Japanese Army invaded the Philippines, causing extensive damage to Manila. Historic structures in Intramuros, including the Santo Domingo Church and the original University of Santo Tomas, were devastated. The most severe destruction, however, came during the American campaign to retake the city from Japan. After the battle, only 5% of the original buildings remained, and 40% of the walls were reduced to rubble.
In 1951, Intramuros was designated a historic monument. Efforts to restore it have been gradual, with the five original gates being returned to their former splendor. However, the ancient walls cannot shield the site from the modern world. Starbucks and McDonald’s outlets now dot the area, and the surrounding moats have been turned into golf courses. Historians fear what further changes may come.
+The Taj Mahal
Built as a mausoleum by Emperor Shah Jahan for his beloved wife, the Taj Mahal required over 20,000 workers, 1,000 elephants, and two decades to complete. Renowned as one of the most stunning wonders of the ancient world, it could be closed to visitors within five years.
Over a decade ago, a study revealed that air and water pollution were causing the pristine white structure to turn a dull yellow. The Indian Supreme Court mandated significant funds for restoration. While the initiative garnered worldwide attention, by 2014, the situation showed no improvement.
Despite claims from monument staff, research indicates a sharp rise in pollutants like nitrogen oxide. Vehicles are banned from approaching within 500 meters (1,640 feet) of the site. However, as Agra expands and traffic surges, the Taj Mahal’s future remains uncertain.
