You know Stonehenge as the historic site in England that consists of stone slabs standing up in a circular form. It once coincided with the sun and seasons but is simply a tourist attraction today. You don’t have to hop across the pond to see something as spectacular as this. In Illinois, the historic attraction that works as a sun dial is known as Woodhenge.

Believed to mark the equinox and solstice sunrises and sunsets, which were then used to signal agricultural and religious activities, Woodhenge is a circular design of timber circles placed in holes.

The original design was constructed between 900 and 1100 CE, though all that was discovered in the 1960s during preparation for a new highway were a series of holes in the ground.

Through tests of the soil, archaeologists determined that red cedar was used to construct the poles that went in the holes. In 1985, replica posts were made and inserted in order to recreate what Woodhenge used to look like.
