Stonehenge is one of the world's most amazing, mysterious wonders. Erected more than 4,000 years ago, the ancient set of stone circles in southern England may be a monument to the dead, a calendar, or something else entirely. Translated into North American Spanish, this elementary-level introduction, filled with vibrant photos and factual text, examines the structure and how it was made. The stones' significance in history and why they were erected are also included. A Wonder Spotlight features the structure's smaller stones, called bluestones. Captions, on-page definitions, and an index support young readers.
