Stonehenge's fabled circle of gigantic stones in Wiltshire, England, still bewilders archaeologists. Carhenge's ring of cars in Alliance, Nebraska, perfectly mimics the original--and bewilders everyone.
Carhenge was built in 1987 by Jim Reinders and his family as a memorial to Reinders' father, who once lived on the farm where Carhenge was constructed. The site is now owned and maintained by a group called Friends of Carhenge.

Legend says Galileo conducted scientific experiments from atop the Tower of Pisa in Italy.

Summer concerts are now held on the grounds near the tower, which was renovated in the 1990s.

The Galleria dell'Accademia in Florence Italy shields Michelangelo's David from the elements. Trees planted in 1973 shield Sioux Falls' replica of the nude from street traffic, appeasing the public, who felt the nudity would reflect poorly on the town's morals. The statue was donated to the city by a Sioux Falls inventor and automobile manufacturer.
