Museum officers have left no stone unturned to get a prehistoric rock back to its moorland home. The Heygate stone with its intricate carved cup and rings returns to Baildon Moor this weekend after a five-year absence to go on permanent public view at Brackenhall Countryside Centre. The stone, which dates back around 5,000 years, was discovered by chance in 2001 by a local landowner out walking in his field. Two years later the man - who was legally entitled to keep the find - donated it to Bradford Council's Museums, Galleries and Heritage Service for safe-keeping. And tomorrow people will get a chance to get up close to the stone which measures around 60cms high and 45cms wide. The Heygate Stone exhibition officially opens at 1pm at the countryside centre in Glen Road. The Council's archaeology expert Gavin Edwards is hoping a big turn out will be there to welcome it back.
