World Heritage Day, celebrated on April 18, aims to raise awareness about the importance of preserving cultural heritage and natural sites around the world. Established by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1982, this day encourages communities to engage in activities that promote the protection of their local heritage. Each year, World Heritage Day focuses on a specific theme related to heritage conservation. Events may include educational programs, cultural performances, and community clean-up initiatives. The day serves as a reminder of the significance of sites listed as World Heritage Sites, which represent humanity's shared history and diversity.
