Benefits (of World Heritage inscription)

Once a country signs the World Heritage Convention, and has sites inscribed on the World Heritage List, the resulting prestige often helps raise awareness among citizens and governments for heritage preservation. Greater awareness leads to a general rise in the level of the protection and conservation given to heritage properties. A country may also receive financial assistance and expert advice from the World Heritage Committee to support activities for the preservation of its sites.
