Which ancient monument consists of stones arranged in a circle with uncertain purpose and origins?

• A. Stone Henge
• B. Avebury Stone Circle
• C. Carnac Stones
• D. Callanish Stones

Answer: (A)

Stones arranged in a circle with uncertain purpose and origins are classic clues to a megalithic monument whose true functions still spark debate. Stonehenge fits this idea best. It’s a circular arrangement of standing stones erected in phases between about 3000 and 2000 BCE in England, featuring lintels and a surrounding ditch. Scholars have long debated why it was built—possible ceremonial use, social gathering, or astronomical observation—but there’s no single agreed answer. Its circle-like layout and enigmatic origins make it the quintessential example of this type. Avebury is also a large circular stone arrangement, but it sits within a broader landscape of ritual sites, so the question of its purpose isn’t captured as neatly by its circle alone. Carnac Stones in Brittany are vast alignments rather than a circle, built in rows. Callanish Stones form a circle on the Isle of Lewis, but Stonehenge remains the most iconic instance widely associated with the mystery of why such circles were erected.
