UNESCO (the United Nations Educational, Scientific and Cultural Organisation) established April 18 as the International Day for Monuments and Sites in 1983 to raise awareness about the diversity and vulnerability of the world’s built monuments and heritage sites, and efforts required to conserve them.
Commonly known as World Heritage Day, it emphasises that more than preserving World Heritage Sites listed by Unesco, tribute should also be given to all cultural heritage places and landscapes of international, national and local significance.
