"The 'most important Neolithic cup and ring marked rock art panel in Europe' is being unearthed for the first time in 50 years on the edge of a housing estate in Clydebank near Glasgow." Source: Heritage Daily.
"The Cochno Stone, dating back to 3000BC, and one of the best examples of Neolithic or Bronze Age cup and ring markings in Europe, is being fully excavated for the first time since it was buried in 1965 to protect it from vandalism."
Note: The stone was buried in the 1960s for its own protection. Earlier this month, University of Glasgow students removed "hundreds of tons of mud" from the site and the Scottish Fire and Rescue Service was called in to wash the mud off the sandstone slab, according to the BBC.
"The aim of the project is to excavate, 3D scan, safely rebury and produce a replica of the Cochno Stone ..," according to the Factum Foundation. Several photographs and detailed maps of the site can be found here.
