"To be included on the World Heritage List, a site must satisfy the
selection criteria adopted by the Committee. A cultural monument
could, for example, be a masterpiece of creative genius, or have
exerted great architectural influence, or be associated with ideas or
beliefs of universal significance, or it may be an outstanding example
of a traditional way of life that represents a certain culture. A
natural site may exemplify major stages of the earth's history, or
represent ongoing ecological and biological processes, or contain the
natural habitats of endangered animals, or it may be a scene of
exceptional beauty."
