First International Congress of Architects and Technicians of Historic Monuments

These Conclusions were drafted at the end of a conference on the restoration of historic monuments and buildings held in Athens in 1931. This document introduced important conservation concepts and principles:

• the idea of a common world heritage;
• the importance of the setting of monuments; and
• the principle of integration of new materials.

The Conclusions were ahead of their time in calling for the reburial of archaeological remains when conservation cannot be guaranteed.
