Cultybraggan Camp, in Comrie, Perthshire once housed a number of Germany's most senior and fanatical Nazis.
The site, made up of 100 corrugated iron Nissan Huts, has undergone a major revamp after the owners, the Comrie Development Trust, received two £10,000 funding packages from the Scottish Government and the Heritage Lottery Fund.
For months the Comrie Heritage Group (CHG), made up of local volunteers, has been hard at work transforming the former guard room at the entrance to the camp into the home of a permanent exhibition.
Self-guide leaflets will be available at the centre, although guided tours will still run on a monthly basis.
Fiona Davidson, chairwoman of the CHG, said: "It is intended not only to be a starting point for exploring the camp but for exploring the wider Comrie area as well and its rich and varied history and characters."
