UNESCO — United Nations Educational, Scientific and Cultural Organization — headquartered in Paris, France. Founded 16 November 1945.
The World Heritage Convention (WHC) was adopted at the UNESCO General Conference on 16 November 1972 and came into force on 17 December 1975. It aims to identify and protect cultural and natural heritage of Outstanding Universal Value (OUV) for present and future generations.
Convention adopted: 1972 · Came into force: 1975 · India ratified: 14 November 1977 — UPSC frequently tests all three dates separately.
OUV means cultural and/or natural significance that is so exceptional as to transcend national boundaries and be of common importance for present and future generations of all humanity. A site must meet at least one of the 10 criteria to qualify.
| Test | Meaning | For |
|---|---|---|
| Criteria | Must meet ≥1 of 10 criteria (i–vi = Cultural, vii–x = Natural) | All sites |
| Integrity | Physical fabric includes all attributes of OUV; adequately sized | All sites |
| Authenticity | Originality in form, design, materials, use, function, tradition | Cultural sites only |
The Tentative List is an inventory of properties that a State Party intends to consider for nomination to the World Heritage List. It is the mandatory first step — a site cannot be formally nominated unless it has been on the Tentative List for at least one year.
UPSC frequently tests: "Inclusion in Tentative List means UNESCO World Heritage status" — this is FALSE. Tentative List ≠ World Heritage List. Tentative listing only means India intends to nominate.
| Event | Date / Year | Significance |
|---|---|---|
| WHC adopted by UNESCO | 16 November 1972 | Treaty established |
| WHC came into force | 17 December 1975 | Legal effect begins |
| India ratified WHC | 14 November 1977 | India eligible for nominations |
| First 4 Indian sites inscribed | 1983 | Ajanta, Ellora, Agra Fort, Taj Mahal |
| India's 44th WHS | July 2025 | Maratha Military Landscapes |
| 7 sites added to Tentative List | 12–13 Sep 2025 | Total Tentative List → 69 |
| Body | Type | Role in WHS |
|---|---|---|
| UNESCO World Heritage Committee | Intergovernmental (21 members) | Final decision on inscription; meets annually |
| UNESCO World Heritage Centre | UNESCO Secretariat (Paris) | Manages nominations, coordinates work |
| ICOMOS | NGO advisory body | Evaluates cultural nominations independently |
| IUCN | NGO advisory body | Evaluates natural nominations independently |
| ICCROM | Intergovernmental body | Expert advice on conservation of cultural sites |
| Archaeological Survey of India (ASI) | Government of India | Nodal agency for WHC in India; submits nominations |
| Ministry of Culture, GoI | Government of India | Policy oversight, approves nominations |
ASI was established in 1861 (under Alexander Cunningham) and manages over 3,693 centrally protected monuments. It prepared and submitted the Sep 2025 Tentative List proposals for all 7 natural sites.
ICOMOS evaluates cultural nominations. IUCN evaluates natural nominations. For mixed sites, both evaluate. Nomination is independently evaluated over 14 months.
World Heritage Day (also: International Day for Monuments and Sites) is celebrated on 18 April every year — organised by ICOMOS.
World Heritage sites must have adequate legislative, regulatory, institutional and/or traditional protection and management in place to qualify for inscription.
India's first 4 WHS (1983): AEAT — Ajanta Caves · Ellora Caves · Agra Fort · Taj Mahal. All inscribed in the same year.

| # | Site Name | State / Location | Key Feature | UNESCO Criteria |
|---|---|---|---|---|
| 1 | Deccan Traps at Panchgani & Mahabaleshwar | Maharashtra (Sahyadri / Western Ghats) | One of the largest volcanic provinces on Earth (~500,000 sq km); ~66 million years old; 2,000m+ thick lava flows; evidence near K-T boundary; within Koyna Wildlife Sanctuary | (viii) Earth's history; (x) Biodiversity |
| 2 | Geological Heritage of St Mary's Island Cluster | Karnataka (Udupi district) | Rare columnar basaltic rock formations (hexagonal); Late Cretaceous period (101–66 million years ago); Vasco da Gama is said to have landed here in 1498 | (viii) Earth's geological history |

Andhra Pradesh contributes 2 of the 7 new sites. Northeast India contributes 2 sites (Meghalaya + Nagaland). All 7 are primarily geological/natural in character.
UPSC loves state-site matching. Remember: St Mary's Island = Karnataka (Udupi) — not Maharashtra or Goa. Erra Matti Dibbalu = Visakhapatnam, AP (Red Sand Dunes). Varkala = Kerala, not Tamil Nadu.
| Site | Key Scientific Concept |
|---|---|
| Deccan Traps | Large Igneous Province (LIP); ~66 Ma volcanic eruptions; K-Pg (K-T) boundary events; basalt stratigraphy |
| St Mary's Island | Columnar jointing in basalt; Late Cretaceous volcanism (101–66 Ma) |
| Meghalayan Caves | Meghalayan Age (4,200 years ago to present) — GSSP at Mawmluh Cave; Holocene stratigraphy |
| Naga Hill Ophiolite | Ophiolite = oceanic crust + upper mantle; records Tethys ocean floor; Himalayan orogeny evidence |

| Category | Count | Change (from 62) |
|---|---|---|
| Cultural | 49 | No change |
| Natural | 17 | +7 (was 10) |
| Mixed | 3 | No change |
| Total | 69 | +7 (was 62) |
Wikipedia (May 2026) shows India's tentative list at 70 properties — some sources say 69. The discrepancy arises from timing of official updates. For UPSC, use 69 (Ministry of Culture official figure, Sep 2025 announcement).
| Rank | Country | Total Sites | Note |
|---|---|---|---|
| 1st | Italy | ~59–61 | Cultural dominant; Colosseum, Venice, Pompeii |
| 2nd | China | ~57–60 | Cultural + natural; Great Wall, Terracotta Army |
| 3rd | Germany | ~53–55 | Cultural dominant; cathedrals, castles |
| 4th | France | ~52–54 | Cultural; Paris, Versailles, Mont Saint-Michel |
| 5th | Spain | ~50 | Cultural; Alhambra, Gaudí sites |
| 6th | India 🇮🇳 | 44 | 36C + 7N + 1M; Taj Mahal, Western Ghats |
| 7th | Mexico / UK | ~35 | Each; Chichen Itza; Stonehenge |
Global rank: India is 6th. Countries ahead: Italy · China · Germany · France · Spain. Note: exact totals for Italy/China/Germany fluctuate between 57–61 depending on source/year. For UPSC, the key fact is India's 6th rank and 44 sites.
| Fact | Detail |

| Category | Definition | India (Inscribed) | India (Tentative) |
|---|---|---|---|
| Cultural | Monuments, buildings, archaeological sites, historic cities of outstanding cultural/historical value | 36 | 49 |
| Natural | Physical/biological formations, geological/physiographic formations, natural sites of scientific/conservation value | 7 | 17 |
| Mixed | Sites with outstanding universal value for BOTH cultural AND natural properties | 1 | 3 |
| Total | — | 44 | 69 |
| Criteria | Type | What It Tests |
|---|---|---|
| (i) | Cultural (i–vi) | Masterpiece of human creative genius |
| (ii) | Important interchange of human values (architecture, arts, town planning) | |
| (iii) | Unique/exceptional testimony to civilisation or cultural tradition | |
| (iv) | Outstanding example of type of building, architectural/technological ensemble | |
| (v) | Outstanding example of traditional human settlement or land use | |

| (ix) | Outstanding examples of significant on-going ecological and biological processes | |
| (x) | Most important natural habitats for in-situ conservation of biological diversity including threatened species |
Criteria (i)–(vi) = Cultural. Criteria (vii)–(x) = Natural. Criterion (vi) is the weakest — UNESCO discourages using it alone. Most of India's 7 new natural sites qualify under (viii) — Earth's geological history. Learn: ICOMOS evaluates (i)–(vi); IUCN evaluates (vii)–(x).
There are currently over 1,223 World Heritage Sites globally (as of 2025) across 168 countries — 952 cultural, 231 natural, 40 mixed.
| List / Program | What It Covers | India Note |
|---|---|---|
| World Heritage List (WHL) | Cultural/Natural/Mixed sites of OUV | 44 sites (India) |

| Warkalli / Laterite Formation | Varkala Cliffs (Kerala) | Mio-Pliocene marine sediments; coastal geomorphology; connects to Kerala's geography questions |
| UNESCO Topic | Linked UPSC Topic | Connection |
|---|---|---|
| Deccan Traps | Geography (Peninsular India), Environment | Western Ghats WHS (inscribed 2012); Koyna Wildlife Sanctuary; K-T extinction events |
| Meghalayan Age Caves | Geography (Northeast), Environment, Science | Holocene epoch; GSSP concept; Meghalaya known for limestone caves (Mawsynram, Cherrapunji) |
| Naga Hill Ophiolite | Geography (Himalayas), Science | Himalayan orogeny; Tethys Ocean; Indo-Eurasian plate collision |

The Meghalayan Age (4,200 years ago to present) was officially named after Meghalaya and formalized in 2018 by the International Commission on Stratigraphy. Mawmluh Cave in East Khasi Hills is the GSSP (Global Boundary Stratotype Section and Point) — the reference cave for this entire geological age.
UPSC Environment questions often link Deccan Traps + K-T boundary + mass extinction. Also link: Deccan Traps → Koyna Wildlife Sanctuary → Western Ghats WHS (already inscribed) — a Prelims statement trap testing whether you know the layers of protection.
India added 7 natural heritage sites to UNESCO's Tentative List on 12–13 September 2025, raising India's total Tentative List count from 62 to 69 (49 cultural · 17 natural · 3 mixed). The announcement was made by India's Permanent Delegation to UNESCO. The Archaeological Survey of India (ASI) prepared and submitted all nomination proposals. The 7 sites are: Deccan Traps (MH), St Mary's Island (KA), Meghalayan Age Caves (ML), Naga Hill Ophiolite (NL), Erra Matti Dibbalu (AP), Tirumala Hills (AP), and Varkala Cliffs (KL).
At the 47th session of the World Heritage Committee held in Paris (July 2025), the Maratha Military Landscapes of India were inscribed as India's 44th UNESCO World Heritage Site. The serial nomination includes 12 Maratha forts — 11 in Maharashtra (including Raigad, Shivneri, Lohagad, Pratapgad, Panhala, Torna, Rajgad) and 1 in Tamil Nadu (Gingee). This reflects the Maratha Empire's sophisticated military architecture and resistance against Mughal expansion.
Moidams — the Mound-Burial System of the Ahom Dynasty (Charaideo, Assam) was inscribed as India's 43rd UNESCO World Heritage Site at the 46th World Heritage Committee session in New Delhi (2024) — notably the session was held in India. Moidams are earthen mounds and vaulted structures used as burial grounds by the Ahom kings of Assam over 600 years.
India also officially nominated Sarnath (Uttar Pradesh — site of Buddha's first sermon) for inclusion in the UNESCO World Heritage List under the 2025–26 nomination cycle. The site had long been on India's Tentative List.
As of 2025, there are 1,223 World Heritage Sites globally across 168 countries — 952 cultural, 231 natural, and 40 mixed. India, with 44 sites, ranks 6th globally — behind Italy (~59–61), China (~57–60), Germany (~53–55), France (~52–54), and Spain (~50).
Earlier in 2025, India had added 6 sites to the Tentative List (raising total from 56 to 62), including: Kanger Valley NP (Chhattisgarh), Mudumal Megalithic Menhirs (Telangana), Ashokan Edict Sites (multiple states), Chausath Yogini Temples (multiple states), Gupta Temples of North India, and Palace-Fortresses of the Bundelas (MP/UP). The subsequent September addition of 7 more raised the count to 69.
For UPSC 2026 (Prelims May 24, 2026): The 7 new natural sites (Sep 2025) and Maratha Military Landscapes (44th WHS, 2025) are both very high-probability questions. UPSC consistently asks about the most recently inscribed site in the exam immediately after inscription. Also likely: Moidams (43rd, 2024) and India's global rank (6th).
| Year | Question Theme | What Was Tested |
|---|---|---|
| 2024 | UNESCO WHS inscriptions 2023 | Santiniketan (2023) vs Hoysala (2023) vs Dholavira (2021) vs Moidams (2024) — year matching |
| 2024 | Heritage Site → Dynasty pairing | Ramappa Temple → Kakatiya · Rani Ki Vav → Solanki (Chandela trap!) · Pattadakal → Chalukya · Nalanda → Gupta-Pala |
| 2023–24 | Santiniketan & Hoysala inscribed same year | Testing if both are 2023 |
| 2022 | Natural sites in India | Which of these is a UNESCO Natural WHS (clubbed with national parks) |
| 2018–20 | Rani-ki-Vav, Mahabodhi, Konark | Correct matching of site + year + dynasty/type |
| Statement | T/F | Reason |
|---|---|---|
| India ratified the WHC in 1972 when it was adopted | ❌ | Convention adopted: 1972. India ratified: 14 November 1977 |
| India has 2 UNESCO Mixed World Heritage Sites | ❌ | India has only 1 Mixed WHS — Khangchendzonga NP (Sikkim, 2016) |
| Inclusion in UNESCO Tentative List grants World Heritage status | ❌ | Tentative List is only a prerequisite for nomination — NOT World Heritage status |
| ICOMOS evaluates both cultural and natural nominations | ❌ | ICOMOS = Cultural (i–vi). IUCN = Natural (vii–x). Each evaluates its own category |
| Western Ghats is a natural WHS spanning 6 states | ✅ | Correct — Gujarat, Maharashtra, Goa, Karnataka, Kerala, Tamil Nadu (2012) |
| All 7 newly added Indian natural sites (Sep 2025) are in South India | ❌ | 2 are in Northeast India: Meghalayan Age Caves (Meghalaya) + Naga Hill Ophiolite (Nagaland) |
| Deccan Traps are part of the Koyna Wildlife Sanctuary | ✅ | Correct — Deccan Traps at Panchgani/Mahabaleshwar are within Koyna WLS |
| India ranks 5th globally in total number of inscribed WHS | ❌ | India ranks 6th (behind Italy, China, Germany, France, Spain) |
| The first 4 Indian WHS were inscribed in 1983 | ✅ | Ajanta, Ellora, Agra Fort, Taj Mahal — all inscribed in 1983 |
| Moidams was India's 44th UNESCO World Heritage Site | ❌ | Moidams (2024) = 43rd. Maratha Military Landscapes (2025) = 44th |
"India ratified WHC in 1972" — WRONG. Convention adopted: 1972. India ratified: 14 November 1977. UPSC tests both years. Do not confuse them.
"Khangchendzonga NP is a Natural WHS" — WRONG. It is India's only Mixed WHS (both cultural AND natural). Natural WHS count = 7, which does NOT include Khangchendzonga.
"All 7 new natural sites are in South/Central India" — WRONG. Meghalayan Age Caves (Meghalaya) and Naga Hill Ophiolite (Nagaland) are in Northeast India.
"Rani-ki-Vav was built by the Chandela dynasty" (PYQ 2024 trap) — WRONG. Rani-ki-Vav (Patan, Gujarat) was built by Queen Udayamati of the Solanki (Chalukya of Gujarat) dynasty, not Chandela.
"India has 44 sites on the World Heritage List and 69 on the Tentative List — both same list" — WRONG. 44 = inscribed WHS (fully recognized). 69 = Tentative List (only intent to nominate). These are completely different lists.
For UPSC 2026: Memorise — Maratha Military Landscapes = 44th WHS (2025) · Moidams = 43rd (2024) · Santiniketan & Hoysala = 41st & 42nd (both 2023) · Dholavira = 40th (2021). The last 4–5 inscriptions are always high-probability questions.
| Rank | Site | State | Year | Type |
|---|---|---|---|---|
| 44th | Maratha Military Landscapes | Maharashtra + Tamil Nadu | 2025 | Cultural |
| 43rd | Moidams — Ahom Dynasty | Assam | 2024 | Cultural |
| 42nd | Sacred Ensembles of Hoysala | Karnataka | 2023 | Cultural |
| 41st | Santiniketan | West Bengal | 2023 | Cultural |
| 40th | Dholavira (Harappan city) | Gujarat | 2021 | Cultural |
UPSC Prelims 2026 is on 24 May 2026. High-priority topics from this page: (1) 7 new natural sites + their states (pair matching likely). (2) Maratha Landscapes = 44th WHS. (3) Tentative List ≠ WHS inscription. (4) 1977 = India's ratification year (not 1972). (5) Khangchendzonga = only Mixed site. (6) India's global rank = 6th.
