It was a drumset?
The pillars that form Stonehenge may have been chosen because they were like sacred “prehistoric glockenspiels”, according to researchers.
The sonorous quality of some of the bluestones used for the monument built between 3,000 BC and 1,600 BC may explain why they were transported 200 miles from Pembrokeshire, Wales, when there were plenty of local rocks to use nearby.
‘Archeo-acoustic’ expert Paul Devereux, the principal investigator on the Landscape and Perception Project, explained the choice to the BBC.
“There had to be something special about these rocks,” he said.
“Why else would they take them from here [Wales] all the way to Stonehenge?”
