How exactly the stones were transported—without the use of wheels—remains a mystery. Perhaps they were pulled by teams of men and animals or moved on giant rollers of wood. However it was done, transporting such enormous stones was a remarkable achievement for the time. Stonehenge was one of the last great monuments built in ancient England. It was abandoned about 3,500 years ago, and because its creators wrote no texts to explain it, they have left us forever with one of history's great puzzles to solve.
