Stonehenge is a megalithic rock monument of 150 enormous stones set in circular pattern, located on the Salisbury Plain of southern England. The outside circle of Stonehenge includes 17 enormous upright trimmed stones of hard sandstone called sarsen; some paired with a lintel over the top. This circle is about 30 meters in diameter, and, stands about 5 meters tall.
