Slide 1
Cahokia became a major centre after about 1050 CE
Cahokia flourished near present-day St Louis and became a major Mississippian centre after about 1050 CE. Its surrounding landscape contained farms, villages and other settlements.

An archaeological site boundary is not the boundary of the society that sustained it. Looking beyond the preserved core reveals the dispersed labour and food production required by a large gathering place. The regional view changes how the centre is understood.
Slide 2
Mounds and plazas organized public space
Cahokia’s mounds and plazas shaped a planned ceremonial and residential landscape. Monks Mound was the largest surviving earthwork within that complex.

Earth construction leaves evidence of choices about location, sequence and labour. A mound’s final outline does not show every building episode, so archaeological layers can reveal changes hidden by the completed surface. Monumental scale and construction history are separate questions.
Slide 3
Gatherings linked the centre with surrounding settlements
Large open spaces such as the Grand Plaza could accommodate public activities. Cahokia brought people together within a wider landscape of outlying settlements.

A gathering place can connect people who do not all live beside it. Seasonal visits and permanent residence would leave different patterns, so estimates of how a centre functioned must consider movement as well as the number of houses nearby.
Slide 4
Some timber-circle alignments tracked sunrise positions
Archaeologists identified timber-circle arrangements at Cahokia, commonly called Woodhenge. Some alignments relate to the changing position of sunrise during the year.

A reconstructed circle makes an interpretation visible to visitors, but reconstruction and surviving remains are different kinds of evidence. Postholes establish where timber stood; proposed uses need additional reasoning. Not every suggested astronomical function is equally well supported.
Slide 5
Decline and abandonment still require several kinds of evidence
Cahokia’s importance declined and the major centre was largely abandoned before European settlement of the region. The reasons are investigated through several kinds of evidence.

A single dramatic explanation can obscure changes that occurred at different times. Comparing settlement patterns, environmental records and construction phases helps test whether pressures coincided. The history of Indigenous peoples continued beyond the occupation of this particular centre.
