Using a Delphi approach to identify managers' preferences for visitor interpretation at Canterbury Cathedral World Heritage Site

Religious heritage sites have seen a remarkable increase in tourist visitation. To cater for the changing, and sometimes conflicting needs of visitors, many religious sites are developing interpretive plans to enhance the provision of on-site experiences. Interpretive plans are normally negotiated between the owners/managers of a site and an interpretation team. This study uses a Delphi approach to ‘negotiate’ owner/management preferences regarding key interpretive topics and themes to inform the development of a visitor interpretive plan for the Canterbury Cathedral World Heritage Site. Sixty-eight interpretive topics were reduced to twenty-one grouped under three themes: past, present and future spiritual development; aesthetic and architectural features; and the cathedral as a working community. The usefulness of the Delphi approach as a means to negotiate a consensus view of owners/managers' interpretive priorities and preferences within a planning context is discussed. Methodological issues arising when using a Delphi approach are also addressed. •A Delphi approach was used to identify and negotiate managers’ interpretive preferences.•After three iterations, 20 topics were selected as priorities.•Three broad themes emerged: faith, aesthetic and architectural features, working community.•The benefits and challenges of using a Delphi approach are discussed.
