Twentieth Century Heritage

ICOMOS International Scientific Committee on 20th Century Heritage (ISC20C)

The ICOMOS ISC20C focuses its efforts on mid to late twentieth-century places that are most at risk, through lack of recognition and inadequate conservation. The multi-disciplinary committee co-ordinates a range of projects, conferences, declarations, and publications to address these issues. New members are always welcome.

World Heritage Papers 5: Identification and Documentation of Modern Heritage. UNESCO World Heritage Centre, 2003 [PDF size: 1.4MB]

In order to gain better understanding, raise public awareness and promote inscription of Modern Heritage, study and evaluation of possibilities, establishment of criteria and selection of properties and sites is needed. To continue and complement the work done by ICOMOS in this field, two meetings were held at UNESCO Headquarters in February and October 2001 respectively to define direction and objectives for a Programme on Modern Heritage. This publication contains the position papers that were written to facilitate the debate during the October 2001 expert meeting. Its aim is to present a framework of conceptual thinking on the significance of Modern Heritage, its preservation and some of the pivotal issues concerning identification and valuation.
