The audio commentary at Stonehenge works well. Whoever supplied the voice is very competent. The description is clear, well delivered. The script is well written. For me the overall effect of what I heard - and I didn't listen to every bit of it, nor can I recall it all - was that the monument retains its mysteries. It was not used for sacrifice. It was not a giant, stone-built, astronomical device. It was not used by druids or any twenty-first century imagined culture. Its builders were skilled, not primitive prehistoric ignoramuses. They were not people like ourselves with our twenty-first century outlook on life. Neither were they stupid or lacking in imagination. Whatever they were building in different forms during different centuries was highly significant. Their structures required knowledge and resources that would challenge us today if we had to build them without modern, powerful tools. What they did was impressive.
