6. Stonehenge II
Stonehenges have been popping up all over America for years. This one in Texas, built in 1989 faithfully replicates the mysterious stones of England. There are also two Easter Island heads on the grounds, giving you a chance to visit both foreign sites in one place, killing two birds with one stone!
