Inscription.
It's a full-size, astronomically accurate replica of the outer ring of Stonehenge made entirely of styrofoam. It was created by artist Mark Cline of Enchanted Castle Studio in 2004, and originally stood in Natural Bridge, VA. Foamhenge underwent extensive repairs and renovations before being installed here at Cox Farms in 2017. While the biggest "sarsen" stones at Stonehenge weigh approximately 25 tons, their styrofoam counterparts weigh about 100 lbs.

What is Stonehenge?
It's a massive monument in Wiltshire, England. It was built in several phases more than 4000 years ago, and it is believed that the stones were brought from many miles away. There are many debated theories about why Stonehenge was constructed. Perhaps it was used as an ancient burial ground, or as a place of healing, maybe for religious ceremonies. One thing is certain, it was built with mathematical precision; the circle matches up perfectly to the direction of the summer and winter solstices and the movements of the moon. So, it may have been used as a calendar to mark the changing seasons.
