Cahokia’s largest Woodhenge circle is so accurately aligned that observers can track solstice sunrise within a day or two, even over a millennium later.
At Cahokia, near modern-day St. Louis, Illinois, archaeologists uncovered large circular arrangements of wooden posts, known as Woodhenges, dating to around 1000 CE. These circles, with diameters up to 410 feet, align with the sunrise and sunset on solstices. Observers could use the post shadows to predict seasonal changes, aiding agricultural planning and ceremonial timing. Unlike stone circles, the wooden posts required regular replacement, indicating ongoing maintenance and observation. The alignment of multiple Woodhenges suggests precise astronomical knowledge and coordinated construction. Cahokia’s society integrated astronomy with social and religious practices, with elites likely controlling observations and rituals. The site demonstrates that large-scale celestial tracking was present in North America long before European influence. Woodhenge serves as both a practical calendar and a spiritual symbol of the cosmos.

Cahokia’s Woodhenges reveal how astronomy supported agriculture, ritual, and social hierarchy. By tracking solar events, communities could regulate planting and harvesting. The circular timber arrangements required careful surveying and long-term observation. Their maintenance reflects ongoing societal investment in astronomical knowledge. The integration of celestial observation with ceremonial structures reinforced political and spiritual authority. Modern reconstructions confirm alignments, highlighting sophisticated empirical practices. Cahokia illustrates the advanced knowledge and cultural importance of astronomy in pre-Columbian North America.
The site emphasizes the interplay between ephemeral materials and precise observation. Woodhenges had to be rebuilt periodically, demonstrating the community’s dedication to maintaining observational accuracy. Solar alignment allowed prediction of seasonal shifts, connecting celestial events to practical and ritual life. The arrangement of multiple circles suggests an understanding of complex celestial cycles. Cahokia underscores the universality of sky observation in human societies. Today, the reconstructed Woodhenge allows visitors to experience prehistoric astronomy firsthand. It stands as a testament to the ingenuity of Native American civilizations in linking sky, society, and survival.
