Cultural heritage tourism (or just heritage tourism or diaspora tourism) is a branch of tourism oriented towards the cultural heritage of the location where tourism is occurring. The National Trust for Historic Preservation in the United States defines heritage tourism as "traveling to experience the places, artifacts and activities that authentically represent the stories and people of the past," and "heritage tourism can include cultural, historic and natural resources."
Culture has always been a major object of travel, as the development of the Grand Tour from the 16th century onwards attests. In the 20th century, some people have claimed, culture ceased to be the objective of tourism: tourism is now culture. Cultural attractions play an important role in tourism at all levels, from the global highlights of world culture to attractions that underpin local identities. (Richards, 1996)
According to the Weiler and Hall, culture, heritage and the arts have long contributed to appeal of tourist destination. However, in recent years 'culture' has been rediscovered as an important marketing tool to attract those travellers with special interests in heritage and arts. According to the Hollinshead, cultural heritage tourism defines as cultural heritage tourism is the fastest growing segment of the tourism industry because there is a trend toward an increase specialization among tourists. This trend is evident in the rise in the volume of tourists who seek adventure, culture, history, archaeology and interaction with local people.
Cultural heritage tourism is important for various reasons; it has a positive economic and social impact, it establishes and reinforces identity, it helps preserve the cultural heritage, with culture as an instrument it facilitates harmony and understanding among people, it supports culture and helps renew tourism (Richards, 1996). As Benjamin Porter and Noel B. Salazar have ethnographically documented, however, cultural heritage tourism can also create tensions and even conflict between the different stakeholders involved (Porter and Salazar 2005).
Cultural heritage tourism has a number of objectives that must be met within the context of sustainable development such as; the conservation of cultural resources, accurate interpretation of resources, authentic visitors experience, and the stimulation of the earned revenues of cultural resources. We can see, therefore, that cultural heritage tourism is not only concerned with identification, management and protection of the heritage values but it must also be involved in understanding the impact of tourism on communities and regions, achieving economic and social benefits, providing financial resources for protection, as well as marketing and promotion.
