“Cultural diversity is the common heritage of humanity,” it was thus proclaimed by the “Universal Declaration on Cultural Diversity,” adopted as one of the basic principles by the General Conference of UNESCO on November 2, 2001. Taiwan’s geographical location, situated as it is in the West Pacific, neighboring the Southeast Asia nations, Japan to its north, Mainland China to its west, the Philippines to its south, is so unique that it was its privilege to always enjoy an important strategic place since ancient times. In the past 400 years, this historical uniqueness of Taiwan has been creating an environment that had cultivated a diversification of everything, including its people, culture and language. This geographical uniqueness is reflected on mountains, hills, plateaus, plains, basins and coastal lines, demonstrating Taiwan’s unique richness and diversification of animals and plants and thus, the high appraisal upon its diversifications both in biology and culture. From 2002 onwards, the Council for Cultural Affairs, the Executive Yuan, began to invite experts from abroad, local government officials and various culturalhistorical enthusiasts eliciting suggestions on how to choose which site has the potential to qualify as a candidate for the World Heritage List. This paper explores the feasible ways to apply for the World Heritage List for Taiwan’s potential sites and the right ways to conserve our cultural heritages, by integrating some current practices that have the characteristics of cultural diversification.
