'The valley is our history and should be kept'
A former opencast coal mine that has been reclaimed by nature could be destroyed by redevelopment, campaigners fear.
They claim the site - on the border of Torfaen and Blaenau Gwent - is now a popular "hidden gem" of a beauty spot and should not reopen.
Last year, Torfaen council rejected plans to remove millions of tonnes of sandstone from the Tirpentwys site.
But the developer, Peakman Limited, has appealed.
