Stonehenge acted like an ancient acoustic chamber

STONEHENGE IS NOW IN AN INCOMPLETE STATE. HOW DID YOU ACCURATELY RECONSTRUCT WHAT IT WOULD HAVE LOOKED LIKE THOUSANDS OF YEARS AGO?

Well, the first thing is as an acoustics professor is not to do it myself, but to talk to the archaeologists because I’m not the expert. We think of Stonehenge as being one fixed thing but it went through many stages. At first it was a large stone circle, maybe 100 metres across, back in 2900 BC. The model we’re looking at is from 2500 BC, so it’s still pretty old. At this point there were 157 stones. Now, quite a lot are either lying on the floor or actually completely missing.
