Principle 2 - Information Sources
Interpretation and presentation should be based on evidence gathered
through accepted scientific and scholarly methods as well as from living
2.1 Interpretation should show the range of oral and written information, material
remains, traditions, and meanings attributed to a site. It should also clearly identify
the sources of this information.
2.2 Interpretation should be based on a well researched, multidisciplinary study of
the site and its surroundings, but should also acknowledge that meaningful interpretation
also necessarily includes reflection on alternative historical hypotheses, local
myths, and stories.
2.3 At cultural heritage sites where traditional storytelling or memories of historical
participants provide an important source of information about the significance of
the site, interpretive programmes should incorporate these oral testimonies—either
indirectly, through the facilities of the interpretive infrastructure, or directly, through
the active participation of members of associated communities as on-site interpreters.
2.4 Visual reconstructions, whether by artists, architects, or computer modelers,
should be based upon detailed and systematic analysis of environmental, archaeological,
architectural, and historical data, including analysis of written, oral and
iconographic sources, and photography. The information sources on which such visual
renderings are based should be clearly documented and alternative reconstructions
based on the same evidence, when available, should be provided for comparison.
2.5 Interpretation and presentation activities and the research and information
sources on which they are based should be documented and archived for future reference
