Authenticity
In heritage conservation, the quality of a historic site or building that makes it a true and credible witness to its history — the principle that original material should be preserved.
Authenticity in heritage conservation refers to the quality that makes a historic building, site or artefact a genuine and credible witness to its own history. A building has authenticity when its fabric, form, materials and spatial qualities are genuinely from the period and tradition they represent — not reconstructed, replaced or falsified.
The Venice Charter (1964) established authenticity as a core conservation value. The Nara Document on Authenticity (ICOMOS, 1994) expanded the concept, recognising that authenticity may be expressed through different attributes in different cultural contexts: for some traditions, material authenticity is primary; for others (including some Japanese and Indian traditions of periodic rebuilding), the continuity of form and craft knowledge may be the authentic quality.
In Indian heritage conservation, the concept of authenticity is complex because many living religious traditions involve periodic renewal of physical fabric as a form of devotional practice — repainting temple sculptures, replastering surfaces, gilding finials. Understanding which elements of a site's authenticity are primary for its significance is essential before conservation decisions are made.
