World Heritage Day (18 April): Theme, History & Indian Sites

World Heritage Day — formally the International Day for Monuments and Sites — is observed worldwide every year on 18 April. Proposed by the International Council on Monuments and Sites (ICOMOS) in 1982 and endorsed by the UNESCO General Conference in 1983, the day is dedicated to raising global awareness about the protection and conservation of cultural heritage, the diversity of heritage expressions, and the efforts required to safeguard monuments and sites for future generations. For India, which now hosts 43 UNESCO World Heritage Sites (as of 2025), the day is an occasion to take stock of conservation efforts by the Archaeological Survey of India (ASI), state departments, INTACH, and community stewards.

For UPSC, World Heritage Day connects to GS Paper 1 — Indian Art, Culture and Heritage, and sections of GS Paper 2 concerning international institutions (UNESCO) and India's engagement with global heritage frameworks.

When and Why Is World Heritage Day Observed?

• Date: 18 April every year
• Proposed by: ICOMOS (International Council on Monuments and Sites) in 1982
• Endorsed by: UNESCO General Conference at its 22nd session, November 1983
• Official name: International Day for Monuments and Sites
• Popular name: World Heritage Day

The date 18 April was chosen at the ICOMOS International Symposium at Hammamet, Tunisia, in 1982 because the month traditionally marks heritage-conservation drives in several member countries.

Objectives

• Raise awareness among the public about the diversity and fragility of cultural heritage

World Heritage Day Themes

Each year, ICOMOS announces a theme to guide global observance. A selection of recent themes:

The 2024 and 2025 themes reflected the urgency of protecting heritage from armed conflict (Ukraine, Gaza, Syria), earthquakes (Turkey-Syria 2023, Morocco 2023), and climate-induced disasters.
