Cultybraggan Camp, near Comrie in Perthshire, once had barbed wire and armed guards to keep 4000 Axis prisoners from escaping.
But now local entrepreneurs are desperate to convert the old Nissen huts into units for industrial or commercial use.
Hess, Hitler's deputy, spent time there in 1941 after flying to the UK to try to broker peace with Britain.
The camp was bought from the Ministry of Defence by the local community from £350,000 in 2007.
Planning proposals have been submitted to Perth and Kinross council, and Comrie Development Trust said most of the inquiries related to using the huts as offices and for industry.
