Stonehenge, in many peoples’ minds, is the most mysterious place in the world. This set of stones laid out in concentric rings and horseshoe shapes on the empty Salisbury Plain, is, at the age of 4,000 years, one of the oldest, and certainly best preserved, megalithic (ancient stone) structures on Earth, but we know almost nothing about who built Stonehenge and why.

My sister and I took a tour to Stonehenge on the way to Bath.
