A Derbyshire museum has been given £4.26m to expand its facilities.
The carvings are of animals, including an ibex
The money will be spent on building a centre of excellence at Creswell Crags, a limestone gorge which contains the country's oldest cave art.
The grant has come from the Heritage Lottery Fund and will pay for a new museum and education centre telling the story of the Ice Age.
Plans are now being drawn up, and if approved, work could start next year, with the centre opening in 2007.
The trust which runs the site will have to find £1m towards the project.
The carvings include a 12,000-year-old representation of bison, horse and birds.
They are the only examples of Palaeolithic cave art in the UK, and the artists who made them would have witnessed a British landscape still being shaped by glaciers.
A local road will also be re-routed to protect the site.
