At the center of the city (in front of Monks Mound) was a Grand Plaza artificially created by leveling off and modifying the ground surface. Mound 72 features over 250 skeletons, some likely sacrificed, others who were elites. Mississippian peoples from Cahokia established colonies or settlements as far north as Aztalan, Wisconsin and in the town of Trempealeau, Wisconsin.

54 DreamingDitto Dang, pyramids were a really good way to make sure your building didn't fall down.
12 RedLockes1 Live 10 miles away. Every school around goes there as field trips. The museum near it is really cool too.
45 readparse I'm trying to be impressed that it has a comparable "footprint" to a full pyramid. But you know, the thing that makes a pyramid impressive is not its footprint. If I lived on a two-acre plot, I could say that the footprint of my land is comparable to the Empire State Building, but nobody would give a shit. I'm not saying that this structure isn't impressive at all. It is, in terms of its age, the fact that it's still here, why it was built, who built it, its preservation today, etc. I think trying to compare it in that way makes it look silly by comparison, and less interesting.
