Speaking as someone who has drawn up plans to build a large trebuchet in my own back yard, I'm always interested when average people put together Really Big Cool Stuff. Australian microbrewery owner Ross Smith is one of those people.

Smith plans to build his very own Stonehenge on his property in Perth. The project, which will include 101 granite stones in two circles and a central altar, will be open to the public once it's complete. In fact, Smith hopes to have the 110-foot circle ready to go before Australia's summer solstice on December 21, and will encourage people to visit and touch the structure. The original Stonehenge, on Salisbury Plain in the United Kingdom, is roped off so that visitors can look but are not allowed to touch the ancient stones.

The site will also include an interpretive center and a kids' playground.

If you can't get to Perth, don't worry. There's another full-size replica of Stonehenge in the United States, located at Maryhill, Washington.
