Discover more about Woodhenge

Located west of Monks Mound, Woodhenge is a fascinating feature of the Cahokia Mounds State Historic Site. This reconstructed circle of wooden posts is believed to have been used by the Mississippian people to track the movements of the sun and mark important dates in the solar year. The posts align with the summer and winter solstices, as well as the spring and autumn equinoxes, acting as a sophisticated calendar.The first Woodhenge was discovered in 1961, and further excavations revealed a series of five circles, each with a different diameter and number of posts. The reconstructed Woodhenge, based on Woodhenge III, was erected in 1985 using the original posthole locations. The posts were made of red cedar, a wood considered sacred by the native people. Some believe the posts may have also been painted red.Woodhenge likely held both practical and religious significance for the Cahokians. In addition to its function as a calendar, it may have been used in religious ceremonies or as an aid in laying out the city. Today, visitors can walk among the posts and imagine the lives of the people who once gathered here to observe the changing seasons. Sunrise observation events are held at the site during the equinoxes and solstices.
