English Heritage explains that the ancient stone ‘core’ was taken from one of Stonehenge’s huge sarsen stones in 1958. Its whereabouts remained largely unknown for the next 60 years, according to officials.
The bizarre course of events unfolded in 1958 when archaeologists were trying to raise a fallen trilithon – two of Stonehenge’s vertical stones supporting a third horizontal stone. Cracks were discovered in one of the vertical stones and, to repair it, holes were drilled and metal rods were inserted. The repairs, which are very hard to see, were “masked” by sarsen fragments found during the excavation, according to English Heritage.
U.K.-based diamond cutting company Van Moppes performed the work, drilling three 1.25-inches (32 millimeters) holes horizontally through the stone. A drilling machine bored out three 0.98-inch (25 mm) diameter cores from the stone.
A company employee, Robert Phillips, kept one of the stone cores, which, for a number of years, was displayed in his office in Basingstoke, U.K. Phillips left Van Moppes in 1976 and later emigrated to the U.S., taking the 42.5-inch core traveled with him. Phillips took the rare stone artifact from Richmond, N.Y. to Chicago to Ventura, Calif. and finally Aventura, Florida.
Experts say that the core offers a fascinating glimpse into the center of the famous stones. While Stonehenge’s smaller bluestones were brought from the Preseli hills in Walls, the origin of the monument’s larger stones is still unknown.
“The last thing we ever expected was to get a call from someone in America telling us they had a piece of Stonehenge,” said Sebire in a statement. “We are very grateful to the Phillips family for bringing this intriguing piece of Stonehenge back home. Studying the Stonehenge core’s ‘DNA’ could tell us more about where those enormous sarsen stones originated.”
Mystery, however, still swirls around the other two cores removed more than 60 years ago
“The other two Stonehenge cores may still be out there somewhere and if anyone has any information, we’d love to hear from them,” Sebire added.
The first monument at the site, an early “henge” monument, was constructed about 5,000 years ago. The world-famous stone circle was built around 2,500 B.C. during the late Neolithic period.
The World Heritage site is known for its alignment with the movements of the Sun – thousands travel to the site in Avebury, Southern England, to mark the solstices in Summer and Winter.
