Three Indian Sites Added to UNESCO World Heritage Tentative List

Why in News?

On 20 October 2026, three Indian properties were announced as additions to UNESCO’s World Heritage Tentative List: the Karst-mud-volcano Complex of Baratang, Andaman Subduction Volcanoes, and the Sirpur Cultural and Archaeological Landscape. The first two are located in the Andaman and Nicobar Islands, while Sirpur is situated in Chhattisgarh. The Archaeological Survey of India (ASI) contributed heritage research and documentation for the properties.

These additions highlight India’s diverse geological and archaeological heritage and create opportunities for future consideration for World Heritage status.

What Is the UNESCO World Heritage Tentative List?

The UNESCO World Heritage Convention was adopted in 1972 to promote the identification, protection and conservation of cultural and natural heritage of outstanding universal value.

A Tentative List is an inventory of properties that a country considers suitable for future nomination to the World Heritage List. Inclusion on the Tentative List is a prerequisite for formal nomination, but it does not guarantee inscription.

The World Heritage Committee, comprising representatives of 21 elected States Parties, decides whether nominated properties qualify for inscription.

India has 45 inscribed World Heritage properties, comprising 37 cultural, seven natural and one mixed property, according to UNESCO’s country profile. The three latest additions are tentative properties, not newly inscribed World Heritage Sites.

Geological Heritage of the Andaman and Nicobar Islands

1. Karst-mud-volcano Complex of Baratang

Located on Baratang Island, this complex features limestone caves and active mud volcanoes. It represents distinctive geological processes and landforms.

• Karst topography: Develops when soluble rocks, particularly limestone, dissolve through the action of water, creating caves, cavities and other landforms.
• Mud volcanoes: Form when mud, gases and fluids rise through underground fractures and escape at the surface.

The complex is significant for understanding geological processes and the evolution of the Andaman island environment.

2. Andaman Subduction Volcanoes

This property comprises Barren Island and Narcondam Island, which are associated with volcanic activity in the Andaman island arc.

Barren Island contains India’s only confirmed active volcano. Its volcanic activity is linked to the tectonic setting of the region, where one tectonic plate descends beneath another in a process known as subduction.

These islands offer opportunities to study volcanism, plate tectonics and the geological evolution of island arcs.

Sirpur Cultural and Archaeological Landscape, Chhattisgarh

Sirpur is located in Mahasamund district on the banks of the Mahanadi River. It is an important archaeological landscape associated with the ancient kingdom of Dakshina Kosala.

The site contains remains of Hindu and Buddhist religious structures, reflecting the region’s historical and cultural diversity. Its 7th-century Lakshmana Temple, constructed primarily of brick and dedicated to Lord Vishnu, is a prominent example of early medieval temple architecture.

Sirpur’s archaeological remains provide evidence of historical religious traditions, architectural development and cultural interactions in central India.

Significance of the New Tentative List Additions

• Geological research: The Andaman sites provide opportunities to study karst processes, mud volcanism and subduction-related volcanism.
• Cultural conservation: Sirpur’s archaeological landscape represents important aspects of India’s religious and architectural history.
• International recognition: Tentative List inclusion can increase awareness of the properties and support future nomination efforts.
• Tourism potential: Responsible heritage tourism may create local economic opportunities.
• Conservation needs: Scientific documentation, site management and protection from environmental and human pressures remain essential.
