Promote building materials, methods, maintenance, and inspections that prevent premature deterioration of our built environment. It is natural for all building materials to deteriorate. Maintenance and interventions in historic structures should mitigate the deterioration of the existing building fabric rather than accelerate deterioration. I propose the following oath, with acknowledgment of the Hippocratic Oath and Cervat Erder’s proposal (Erder 1977):
The procedures and materials selected will be for the benefit and respect of our cultural heritage. We will give no harmful treatment, nor counsel such, nor aid in the deterioration or demolition of any monument. As stewards of our heritage and for the benefit of society, we will spurn harmful practices and document all steps taken.
