WHY THE HISTORIC TowN oF VIGAN wAS INScRIBED IN THE UNESCO WORLD HERITAGE LIST?
Towards the end of November 1999, the UNESCO World Heritage Convention met in Marrakeeh, Morocco to decide which of the sites and monuments proposed by countries that have adhered to the World Heritage Convention should be included in the World Heritage List. The selection process is quite difficult for the World Heritage Committee, composed of specialists from 21 countries elected from among the nations that have signed the Convention, which determined how each site or monument, as opposed to another, be judged to form part of the World Heritage and what constitutes the exceptional and universal value of a cultural treasure.
