FOSM’s Summer Solstice Celebration Festival

Our annual festival highlights the area’s history, heritage, ecology, as well as the multitude of aspects associated with the Serpent Mound Park. The Great Serpent Mound effigy, built by the Ancient Indigenous Peoples, incorporates alignments to the rising and setting of the sun and moon on the solstices and equinoxes. The summer solstice sunset alignment is through the open jaws and across the oval.
