Heritage interpretation refers to all the ways in which information is communicated to visitors to an educational, natural or recreational site, such as a museum, park or science centre. More specifically it is the communication of information about, or the explanation of, the nature, origin, and purpose of historical, natural, or cultural resources, objects, sites and phenomena using personal or non-personal methods. Some international authorities in museology prefer the term mediation for the same concept, following usage in other European languages.
Heritage interpretation may be performed at dedicated interpretation centres or at museums, historic sites, parks, art galleries, nature centres, zoos, aquaria, botanical gardens, nature reserves and a host of other heritage sites. Its modalities can be extremely varied and may include guided walks, talks, drama, staffed stations, displays, signs, labels, artwork, brochures, interactives, audio-guides and audio-visual media. The process of developing a structured approach to interpreting these stories, messages and information is called interpretive planning. The thematic approach to heritage interpretation advocated by University of Idaho professor Sam Ham, the National Association for Interpretation, the US National Park Service, and others, is considered best practice.
