LONDON, September 14 (Hfrance.fr) - Vital repair work to repair cracks and holes in prehistoric megaliths at Stonehenge begins Tuesday in one of the world's largest conservation worksation to the world heritage site for decades, according to English Heritage.
The work of Stonehenge, one of the most famous prehistoric monuments in the world including the stones date back some 4,500 years, will address problems caused by erosion and repair previous repairs that were uncovered by detailed laser scans.
"Stonehenge is unique among stone circles because of its special lintels and gaskets used to secure the lintels in place, " Heather Sebire, English Heritage Senior Curator for the site.
"Four and a half thousand years of being rocked by wind and rain has created cracks and holes in the stone surface, and this vital work will protect the features that make Stonehenge so distinctive.
The works, which will see scaffolding erected for perputting access to the top of the stones, the largest of which is about 30 feet (9 meters) high, will prevent existing cracks from enlarging and replace the concrete mortar used for repairs in the 1950s and 1960s lime mortar.
As part of the project, Richard Woodman -Bailey, 71, who placed a coin under one of the stones giants in 1958 during the last major conservation works when he was only eight years old, will return to place a newly minted 2-pound coin in the new mortar, English Heritage said.
Woodman-Bailey's father was the chief architect of ancient monuments who directed the restoration work. Michael Holden Editing Report by Raissa Kasolowsky
