Which US landmark was once one of the largest cities in the world? Uncovering the Hidden History of Cahokia Mounds

When you think of ancient metropolises, your mind might wander to Rome, Athens, or even sprawling cities in Mesopotamia. But what if I told you that one of the most significant urban centers of its time, a city that rivaled London and Paris in population, once thrived right here in the United States? The answer to the question, "Which US landmark was once one of the largest cities in the world?" points to a remarkable and often overlooked archaeological site: Cahokia Mounds State Historic Site in Illinois.

Located just across the Mississippi River from modern-day St. Louis, Missouri, Cahokia was once the center of a complex and influential Native American civilization that flourished between roughly 1050 and 1350 CE. At its peak, around 1200 CE, Cahokia is estimated to have been home to anywhere from 10,000 to 20,000 people, and possibly even more. This makes it one of the largest and most sophisticated pre-Columbian settlements north of Mexico.

The Grandeur of a Lost City

Cahokia wasn't just a large settlement; it was a meticulously planned urban center. The people who built and inhabited it, often referred to as Mississippians, were advanced agriculturalists and skilled craftspeople. They constructed monumental earthen mounds, a testament to their organizational capabilities and deep understanding of their environment.

The most prominent of these mounds, and the centerpiece of the site, is known as Monks Mound. This colossal structure is an astounding feat of engineering. It measures an incredible 100 feet high, 995 feet long, and 775 feet wide, covering an area of over 14 acres. To put that into perspective, Monks Mound is larger at its base than the Great Pyramid of Giza in Egypt! It was built by humans carrying millions of basketfuls of earth, a monumental undertaking that would have taken generations to complete.

Monks Mound served as the central administrative and ceremonial hub of Cahokia. At its summit, archaeologists believe a large temple or palace complex once stood, likely the residence of the paramount chief or ruler of Cahokia. From this elevated vantage point, the rulers could oversee the vast city and its surrounding territories.

Beyond Monks Mound: A Thriving Metropolis

While Monks Mound is the undisputed star, Cahokia was a sprawling urban landscape with a variety of structures and features:

• Residential Areas: Thousands of homes, typically small, thatched-roof dwellings, were clustered in neighborhoods around the central mounds.
• Plazas: Large, open, cleared areas, such as the Grand Plaza located in front of Monks Mound, served as gathering places for public ceremonies and markets.
• Woodhenge: A series of large, circular arrangements of wooden posts, known as Woodhenge, were used as astronomical observatories. These were likely employed to track the solstices and equinoxes, playing a crucial role in the agricultural calendar and ceremonial life. One of the most impressive of these was a circle of 48 posts that would have functioned as a solar calendar.
• Defensive Structures: Evidence suggests that parts of the city were enclosed by a palisade wall, indicating potential concerns about defense or a desire to demarcate the urban core.
• Other Mounds: Over 100 mounds, of various shapes and sizes, have been identified within the Cahokia site. These served diverse purposes, including burial mounds, platform mounds for residences or temples, and ridgetop mounds.

The influence of Cahokia extended far beyond its immediate borders. Artifacts found at the site, such as copper ornaments from the Great Lakes and shells from the Gulf Coast, demonstrate extensive trade networks that connected Cahokia with distant regions of North America.

Why Did This Great City Decline?

The reasons behind Cahokia's eventual decline and abandonment are still debated among scholars. However, several plausible theories exist:

• Environmental Degradation: The intense agricultural practices and the sheer population density may have led to soil exhaustion and deforestation, making it difficult to sustain the large population.
• Climate Change: Shifts in climate, such as periods of drought or flooding, could have severely impacted crop yields and the availability of resources.
• Social and Political Factors: Internal strife, the depletion of resources, or the rise of new competing centers of power could have contributed to the city's downfall.
• Disease: While direct evidence is scarce, it's possible that diseases, exacerbated by crowded conditions, played a role.

By the early 14th century, Cahokia was largely abandoned. The reasons are complex and likely a combination of the factors mentioned above. The descendants of the Cahokian people, however, continued to thrive in other areas, and their cultural legacy lives on in various Native American tribes of the region.

Visiting Cahokia Mounds Today

Today, Cahokia Mounds is a UNESCO World Heritage site, a protected area that allows us to glimpse into this fascinating chapter of American history. Walking among the mounds, especially climbing to the top of Monks Mound, offers a unique perspective on the scale and ambition of this ancient civilization.

The interpretive center provides invaluable context with exhibits on the Mississippian culture, the construction of the mounds, and the daily life of Cahokia's inhabitants. It's a powerful reminder that the story of America is far older and more diverse than many realize.

In Conclusion

So, to answer the question, "Which US landmark was once one of the largest cities in the world?" the answer is definitively Cahokia Mounds. It stands as a silent, yet powerful, testament to the ingenuity, complexity, and organizational prowess of a Native American civilization that created an urban marvel centuries before European arrival.

Frequently Asked Questions about Cahokia Mounds

How large was the population of Cahokia at its peak?

Estimates suggest that Cahokia's population ranged from 10,000 to 20,000 people, and possibly even more, around the year 1200 CE. This placed it among the most populous urban centers in the world at that time.

Why are the mounds made of earth?

The Mississippian people built their mounds using earth because it was a readily available building material in their environment. They used baskets to carry and deposit millions of cubic feet of soil over many years to construct these monumental structures, which served as platforms for important buildings like temples and residences, as well as burial sites.

How did Cahokia compare in size to European cities of its time?

At its height, Cahokia's population was comparable to, and likely surpassed, that of many major European cities of the same period, such as London or Paris. This highlights its significance as a major urban center on a global scale.

What happened to the people who lived in Cahokia?

The reasons for Cahokia's abandonment around the 14th century are not entirely known, but scholars believe it was likely a combination of factors, including environmental degradation, resource depletion, climate change, and possibly social or political upheaval. The descendants of the Cahokian people dispersed and continued to thrive in other areas.
