World Heritage Day, also known as the International Day for Monuments and Sites, is celebrated every year on April 18. It was established by International Council on Monuments and Sites in 1982 and later approved by UNESCO. The day aims to raise awareness about the importance of preserving cultural heritage across the world.

Heritage sites include monuments, buildings, natural landscapes, and places of historical, cultural, or scientific importance. Famous examples include the Taj Mahal, Great Wall of China, and Machu Picchu. These sites represent the rich history and traditions of different civilizations.

The main purpose of World Heritage Day is to encourage people to protect and conserve these valuable sites. Many heritage structures are under threat due to pollution, urbanization, natural disasters, and human negligence. Governments and organizations work together to restore and maintain these sites so that future generations can learn from them.

In India, a country rich in cultural diversity, World Heritage Day is celebrated with activities like heritage walks, educational programs, and exhibitions. Students and citizens are encouraged to visit historical places and understand their significance.

In conclusion, World Heritage Day reminds us of our responsibility to protect the treasures of the past. Preserving heritage is not just about saving buildings, but also about keeping our culture and identity alive.
