Collyweston slate mine reopening for the first time in more than 40 years
A mine is getting ready to produce slate after a 40-year wait.
Collyweston slate, named after the Northamptonshire village in which it is produced, has been used on illustrious buildings for more than 600 years.
The mine is being reopened because supplies are running low.
King's College, Cambridge, will be the first to benefit when it replaces its crumbling roof tiles.
