World Heritage Day, also known as the International Day for Monuments and Sites (IDMS), is celebrated on April 18 every year. Its goal is to encourage individuals and local communities to cherish their cultural heritage. In addition to monument preservation, the day seeks to raise public awareness of the diversity and fragility of cultural assets.
The theme for World Heritage Day 2025 is "Heritage under Threat from Disasters and Conflicts: Preparedness and Learning from 60 Years of ICOMOS Actions”.
As of October 2024, there are 1,223 World Heritage Sites across 196 countries (952 cultural, 231 natural, 40 mixed).
