The International Council on Monuments and Sites (ICOMOS) works through its International Scientific Committee on Twentieth-Century Heritage (ISC20C) to promote the identification, conservation and presentation of Twentieth-century heritage places.

ICOMOS is an international non-government organisation of conservation professionals which acts as UNESCO’s adviser on cultural heritage and the World Heritage Convention.

The Madrid Document makes an important contribution to one of the ISC20C’s current major projects, that of developing guidelines to support the conservation and management of change to Twentieth century heritage places.

The Madrid Document was developed by members of the ISC20C during 2011 and it was first publically presented at the “International Conference Intervention Approaches for the Twentieth Century Architectural Heritage”, held in Madrid in June 2011. The conferenec was  organized by  ISC20C Vice President Fernando Espinosa de los Momteros in association with the Campus Internacional de Excelencia Moncloa – Cluster de Patrimonio, and with the colaboration of the Escuela Técnica Superior de Arquitectura de Madrid (ETSAM). Over 300 international delegates debated and amended the initial draft of the document, which was unanimously adopted by the conference delegates on June 16th, 2011 at the Palacio de Cibeles, before the City of Madrid and Ministry authorities.

Currently, the Madrid Document refers only to architectural heritage and specifically, looks carefully at guiding intervention and change, but  the ISC20C is considering broadening the document’s scope to encompass guidelines for all types of heritage places of the Twentieth Century.

After following the usual ICOMOS processes for the development of conservation guidelines and principles, the final document may take its place among ICOMOS international doctrine.

We invite comments on the Madrid Document, to assist the preparation of a second edition. Comments may be submitted in English, French or Spanish, addressed to the Secretary General of ISC20C: isc20c@icomos-isc20c.org
