Cahokia Mounds was the first of the three ‘earthen mounds’ WHS I planned to visit on this US trip. Honestly, I did not have high expectations. I was anticipating some Viking-style heaps of soil covered by grass, revealing few clues of what had happened there in the past. But this is so much more impressive.

Already while reading up on the site beforehand I noticed similarities with Teotihuacan (which is much older by the way and had ten times as many inhabitants, to put it in perspective). There are a number of drawings used in the interpretation of the site that show what ‘Cahokia City’ may have looked like (see top photo). You have this gigantic mound (Monks Mound) which probably was the ceremonial center and residence of the chief. It is slightly larger than the Temple of the Sun in Teotihuacan. There was a Grand Plaza as well as numerous funerary tumuli. Over 10,000 people are believed to have lived in the city in its heydays around the year 1100.

This is also a WHS ‘connected to a road’ – you can’t get away from the fact that a major road crosses the site, separating the Monks Mound and the reconstructed Woodhenge from the rest of the mounds. This is the US, so no one apparently has thought of at least adding a pedestrian crossing and some speed bumps to let people safely cross on foot. The same road (well, a forerunner: the National Road) however has been instrumental in the fact that we still can enjoy the remains of Cahokia. Legislation and activism in the 1950s and 1960s raised the awareness of the importance of the site and some of the money allocated for highway construction was used in the salvage operations for Cahokia.

This brings up the subject of ‘reconstructions’. As most original structures such as living quarters and the city wall were made of wood, nothing of these remains. A few stock posts and a woodhenge have been reconstructed. The earthen mounds are largely original, but some have been restored after they had been plowed over when the area still was in agricultural use.

The visitor center is undergoing restoration at the moment, so the exhibition is not open and also there are no (audio) guided tours available. You can pick a trail map and a booklet from one of the boxes outside. When you follow the yellow hiking trail you will pass the site’s highlights, each of which has an information panel. I found the interpretation of the site pretty well done, although overall the knowledge about what was going on at Cahokia is limited (and it makes you wonder whether the interpretations are overly inspired by better-documented Mesoamerican examples). The site officially is open ‘from dawn til dusk’, but due to its location by the side of the road and it being unfenced, it is in fact accessible 24x7.

It's rather striking to compare and contrast the first two US World Heritage Sites dedicated to pre-Columbian North American civilizations. Mesa Verde, in the American Southwest, retains impressive adobe structures built into cliffsides, where Pueblo civilizations would live while farming on the fields above. Cahokia Mounds, on the other hand, retains only earthen mounds left behind from what was once the most advanced civilization north of Mexico. Mesa Verde was built in brick and stone, while structures at Cahokia Mounds were made of wood, which did not last through the centuries. Mesa Verde had the advantage of protection from the US federal government as early as the late 19th century. Cahokia Mounds, on the other hand, was in a prime location on the Mississippi River for European settlers. These settlers did not help in maintaining the integrity of the site; protections for Cahokia Mounds only came in the early 20th century. All this is to say that while it is admirable that the US has protected the heritage of pre-Columbian civilizations across the nation, visitors are more likely to be impressed with sites in the West than the East.

I traveled to Cahokia Mounds for a third visit on a road trip this past summer. The day was sunny and clear, and I was glad I started out in the morning, since the area around Cahokia Mounds gets rather hot and muggy on summer afternoons, and there is little in the way of protection from the sun around the mounds. I completed a circuit that first took me from the interpretative center across the road to a partially reconstructed stockade, built to show how the ancient city used to be protected. From there, I hiked up to Monk's Mound, the largest pre-Columbian earthwork in the Americas. Although a temple is believed to have once stood atop the mound, there are no visible remains; instead the summit offers a good view of the nearby city of St. Louis, on the opposite side of the Mississippi River. I continued from Monk's Mound on a trail around some smaller mounds and reached a site dubbed Woodhenge, where it is believed the Mississippian culture over time used rings of cedar posts as solar calendars. As the day was getting warmer, I crossed the road again, and hurried past the remaining mounds to the interpretative center, which was thankfully open, though with limited capacity due to COVID restrictions. The center gives an excellent overview of the Mississippian culture, as well as the early history of Cahokia Mounds, and I highly recommend a visit there.

Cahokia Mounds is not one of the most visually compelling World Heritage Sites in the United States, but it does have an impressive history, and is worth a visit for anyone traveling to St. Louis, Missouri.

Logistics: Cahokia Mounds is on the eastern side (or Illinois side) of the Mississippi River from the city of St. Louis, Missouri; private transportation is recommended.

Hard to rate this one, since it depends on what metric you're going for. The site itself is pretty enough, and Wizard's Mound offers great views of the surrounding countryside and St. Louis, but archaeological sites are always a tough sell unless you study the stuff. Also, walking around an open field at -15C was not super fun.

Besides the relatively boring tourist aspect (though the museum is nice enough), this is a really important site. Not just because it had been the largest city in the US until Philadelphia eclipsed it in the late 1700s, but because that city had been built by indigenous people. The size, importance, and longevity of the settlement kind of remind me of the early writings on Great Zimbabwe: white settlers couldn't believe that the "savages" they'd fought upon colonization could have been capable of building such magnificent earthworks. To those who with an open mind (beyond what is taught in school), it really blows open the concept of "American history" to a much longer and more interesting timeline. Basically, what is now the US was populated by sophisticated, cosmopolitan cultures that were utterly wiped out over centuries of violence fueled by a superiority complex. It's a powerful lesson, and the site is possibly the best example of this proud indigenous history in the US.

On the rainy day of May, after saw the impressive Eero Saarinen’s Gateway Arch and tried toast ravioli in central St Louis, I drove to Collinsville, Illinois to see the World Heritage Site, Cahokia Mounds. After got out from highway, I entered the archaeological zone. The road signs to Woodhenge and the gigantic Monks Mound were clearly visible along the route, but I decided to visit the museum and interpretive center first in order to get deeper understanding on Cahokia. Despite the rain, the carpark of the museum was surprisingly almost full.

Inside the museum, there was a very good replica of ancient village that show how ancient people of Cahokia lived. The story of sun worshipper society was a little Inca-liked to me, but still very interesting to know the existence of Mississippian culture which I have never heard before. The museum was indeed very nice, too bad that my visit happened to be in the same time of school trip, so the place was very noisy and full with children who did their school trip reports. Because of the rain, there were no children allowed to walk outside the museum, so to avoid the crowd I decided to walk along the trail to see the mounds. The walk really reminded me Gyeongju’s Tumuli Park with big and small mounds in the park. The twin mounds were maybe the most interesting one for its bigger size. Along the trail, I could see the Monks Mounds but there was no route from the museum to the great mound, so I backed to my car and drove to the site instead. The Monks Mound was the most impressive sight of Cahokia, the ground size was truly remarkable and larger that the Pyramid of the Sun in Teotihuacan I saw last year. I had to admit that the engineering of ancient Cahokia people was a real world wonder. According to the information in the museum, the Monks Mound was the platform for residence of priests or chieftain palace that carried sun worshipping ceremony. As mentioned by other reviewers, the view on top of Monks Mound was quite nice, even with shower rain, I still could see the view of downtown St Louis. When I walked back to carpark the rain became heavier and heavier, so that I decided to cancel my idea to see Woodhenge and better backed to St Louis.

It was a nice two hours visit to Cahokia. The site was very interesting as the Mississippian culture was quite unknown. I surprised to learn the news of financial problem of the site. The problem seems to be that the site located in Illinois, not Missouri. Most of visitors to Cahokia are actually come from Missouri, I talked with the students and their school are in St Louis and there is no fee to visit the place, so Cahokia relies only on budget from Illinois, and the Missourians don’t fully want to provide financial support to help other historical site in other state! It would be a shame that the interpretive center has to close down in certain period of year as without this center to explain, visiting Cahakia will be totally lost in understanding of this site’s outstanding universal value. At last I don’t know why our regular reviewers, Ian Cade and Kyle Magnuson, picked the almost similar photos of Monks Mound but in different season, summer and autumn! Well I decided to continue this nice practice with the similar one but in the rainy late spring version!

Cahokia is worth a stop for anyone visiting St. Louis. It is a nice side trip from the city. If you are visiting the area solely for the Cahokia Mounds you may be disappointed. The site is deserving of its place on the world heritage list, the site Iis important. However, as a tourist site Cahokia does not offer much besides mounds that are evidence of a unique civilization.

The climb up the stairs to the top of the mound gives little knowledge of the site without being paired with the video in the visitor center.

The museum should not be overlooked, it is an excellent source of information about the site, and the video provides a insightful view of what makes Cahokia special. Overall, I enjoyed the experience as I'm especially interested in Native American history. For me 1.5 hrs was sufficient to enjoy the museum and site itself. On a clear day from the mound top you can see St. Louis in the distance.

Mound Building WHS

Cahokia is now one of three mound building WHS in the United States, some differences to consider. Pairing these sites together with other attractions is ideal. Poverty Point is the oldest of these properties and the most rural. Cahokia can be easily paired with St. Louis and even Chicago to the North. Hopewell, which is a serial property is found scattered between Cincinnati and Columbus, Ohio.

The largest pre-Columbian city north of Mexico, Cahokia is a major archaeological site (it had a population larger than London's in the 13th century), but little known even within the US. For those with a reasonably big interest in history and archaeology, this is a very rewarding place to visit, but be sure to see the excellent museum in the visitor centre, and to join a (free) guided tour (very informative). Otherwise all those hills scattered around the area won't make much sense to you. If you climb atop the largest one, called Monk's Mound, you can even see the skyline of St. Louis and the Gateway Arch. The site can be reached by public transport as well (metro train to East St. Louis, then bus to Collinsville, then a 25-minute walk - not as bad as it sounds). I was pleasantly surprised that they really highlighted their WH status - not a matter of course in the US. There was even a WH flag next to the American one at the entrance - never seen one of those before...

The site is actually the largest Pre-Colombian city north of Mexico and formerly had a population of around 15,000, the main aspect of the park are the 69 man made mounds, the largest of which is the Monks Mound (pictured) which is around 100ft tall. This is the most impressive part of the site and from the top you get a good over view of most of the site, and you can see central St. Louis. The rest of the site is spread around and basically consists of a lot of grass mounds that vary in size and a ‘woodhenge’ calendar, if I am being honest it was not hugely impressive to see but it was very interesting none the less.

The interpretive centre has some interesting exhibits and a recreation of the houses that would have stood in the city, also there was an extremely good video which gives a great introduction, and talks about how and why the civilisation evolved in this area, it made me think of the things I read about evolution of civilisation in Mesopotamia at the University of Chicago the day before. The reasons for the development of a city here were similar as were the structures which were a little like basic Ziggurats. The interpretive centre is closed on Mon-Tue but the park is open all the time.

This site is just outside St. Louis and I managed to see it on a long day trip down from Chicago. If you are here it is worth going in to St Louis and the road takes you over the Mississippi on or next to the Eads Bridge which is on the US’s prospective list. Also there is the Eero Saarinen’s Gateway Arch, well worth a visit and the Anheuser-Busch Budweiser Brewery, which is nice, shame about the beer though!

Cahokia Mounds is located just east of St. Louis, MO. This was the last of the USA world heritage sites that I visited. The natural site was very interesting. Some of the mounds are more than 100 ft. tall. The site contains at least 70 mounds that are between 800 and 1000 years old. The entire site (a large residential city of the Mississippean Native Americans) was almost completely surrounded by a very impressive fortress.

The museum at the mound site is quite good. It has actual artifacts unearthed at the site as well as representations of the city. Several grave sites have been excavated here. One, a high ranking man, was wrapped in a cloak covered with more than 10,000 round shells sewn into the shape of an eagle.

The site is all the more interesting since it presents a fascinating contrast between present day Mississippi river life and that of a millenium ago. (You can see downtown St. Louis and the Gateway Arch from the top of the Monk's Arch)

I went to the Cahokia Mounds pretty much as a last minute visit before heading out of Saint Louis, I just saw the sign and decided to go there. I am glad I did. I had no idea this even existed but am glad I took the time to learn about it. It was a very intresting site, did not take long to go through but was very informative. I am generally not intrested in archeological stuff but even I found it intresting. I recommend taking an hour out of your day as you pass by and visit it. It is worth the look and it's free (although you can spend money in thier gift shop, or through donations if you want)
