It ’s one of the groovy archaeological mysteries of all clock time : How did Neolithic people build Stonehenge — a monumental , bluestone structure in an area where no Stone of that kind can be found ? AsCNNreports , a new study answers some of the questions the site promote and lay other theory to rest .
The first stage of Stonehenge , locate in what ’s now Salisbury , England , was build up roughly 4000 year ago . Archaeologists have known for a while that the bluestone used to make Stonehenge originated from quarries in Pembrokeshire , Wales , 150 miles aside , but how the stones arrived at their current spot is less clear . agree to one theory , mankind spentmonthstransporting the materials , possibly with wooden sleighs on rolling wave , oxen , or river mass .
Other experts importune that it would have been impossible to transport the 25 - ton rocks such a great distance using crude applied science . Instead , they say the stones were placed there by frigid activity .
Thenew studypublished in the journalAntiquitydebunks that idea . Archaeologists and geologists from the UK studied the smaller rocks used to build Stonehenge and pegged them to two target in the Preseli Hills of Wales . Upon inspect the internet site , they discovered traces of pecker , gem hoagie , and moil activity . The grounds dates back to 3000 BCE , the same time when construction on Stonehenge start .
The resultant role also drive away antecedently held notion have-to doe with the rocks ' origins . Though it ’s wide take that the gemstone come from the Preseli Hills , this study is the first to delineate them to two specific quarries on the N side of the hills — Carn Goedog and Craig Rhos - y - felin . It was thought for intimately a one C that the rocks were dig up from the opposite side .
The research squad order their determination propose that stuff used to make Stonehenge were moved by purposeful human activity rather than freak natural forces . But the field of study still leave some enquiry unanswered , such as how the ancient peoples were able to transport the rocks 150 miles after digging them up . The fact that the rocks came from the due north side of the Preseli Hills suggests they were dragged over land rather than transported by river — though the precise method used remain a mystery story .
