The Discourse of Tourism and National Heritage: A Contrastive Study from a Cultural Perspective presents an in-depth research study in the field of online tourism promotion. It focuses on the national online promotion of UNESCO World Heritage Sites, on two different types of websites – institutional and commercial – from three countries, Romania, Spain and Great Britain. The book analyses the way in which each country combines various modes to create a virtual brochure with a promotional message from both institutional and commercial positions. In doing this, it studies the organization of the websites and their webpages, as well as the lexico-grammatical and visual features of their promotional messages. The theoretical framework used is Systemic Functional Linguistics (Halliday 1985, 1994; Kress and van Leeuwen 1996, 2006; Halliday and Matthiessen 2004). The results are compared in relation to the types of websites and to the countries in which they were produced. These are further interpreted from a cultural perspective, showing that the findings can be accounted for by cultural variability, in particular the dimension of context (Hall 1976, 1990, 2000).
