Cliffhanger centre plan for Aberdeen's Rubislaw Quarry revealed
Images of plans for a heritage and visitor centre overlooking Aberdeen's Rubislaw Quarry - one of Europe's largest man-made holes - have been unveiled.
The quarry - credited with giving Aberdeen its Granite City name - closed in 1971.
Developers hope to build a centre hanging over the top of the quarry, which could be completed by 2014.
It was bought by Sandy Whyte and Hugh Black in 2010.
David Halliday, of architects Halliday Fraser Munro, said: "This is a fantastic opportunity to showcase an important part of Aberdeen's history.
"The innovative and dynamic design complements the existing dramatic setting and will give visitors an unforgettable experience."
