Front Lawn Stonehenge
Fred and Pam Levin decided that their horse farm barn would make a perfect staging area to build a Stonehenge. Made of styrofoam and stucco, it debuted on their grassy lawn in 2007. Its "stones" are 13 feet tall, slightly smaller than those in England, but otherwise the Levins have a good looking replica. Its only downside is that it's on private property and trespassing is forbidden -- but like any good Stonehenge, it can easily be seen from the road.
The Levins also have a Cretan labyrinth and African medicine wheel on the property, and reportedly had their Stonehenge created to match the measurements of the original.
