Missing piece of Stonehenge returns after 60 years

A piece of stone drilled from Stonehenge, a mysterious circle of ancient stones in southern England, has been returned to the site 60 years after being removed during archaeological excavations, English Heritage said on May 8.
The cylinder, which is 1.08 meters long and has a diameter of 25 millimeters, was taken from one of the monoliths in 1958 when the cracked stone was strengthened with metal rods.
Robert Phillips, an employee of the diamond cutting firm Van Moppes which carried out the work, kept the extracted stone core and later took it to the United States when he emigrated there, English Heritage said.
"Studying the Stonehenge core's 'DNA' could tell us more about where those enormous sarsen stones originated," she said.
Radiocarbon dating shows that Stonehenge, a ring of about 4-metre-high standing stones in Wiltshire, southern England, was constructed 4,000-5,000 years ago.
There is no definitive answer as to why it was built or what purpose it served, though theories suggest it could have been a religious site or an astronomical observatory.
Thousands of pagans, druids and revelers still gather at the site to see the sun rise on the summer and winter solstices each year.
Stonehenge's smaller bluestones were brought from the Preseli Hills in south-west Wales but the precise origin of the much larger sarsens is unknown.
A British Academy and Leverhulme Trust project, led by professor David Nash of the University of Brighton, is investigating the chemical composition of the sarsen stones in order to pinpoint their source, English Heritage said.
They believe the rediscovered core presents a unique opportunity to analyze the unweathered interior of a stone.
