Port Blair: Capital and Administrative Centre of the Andaman and Nicobar Islands

Geography and climate

Port Blair occupies a natural harbour and is surrounded by coastal plains and mangrove-lined inlets. The climate is tropical maritime: warm and humid with a monsoon season that brings most annual rainfall. Coral reefs, seagrass beds and varied marine life lie in the waters around the town, while forested hills and protected areas are found on nearby islands and reserves.

History and heritage

The town developed under British colonial rule as a penal settlement and administrative outpost; remnants of that era form part of Port Blair's historic identity. The Cellular Jail, a colonial-era prison complex, is one of the best-known heritage sites and is preserved as a memorial to Indian freedom fighters. Over the 20th century Port Blair evolved into the principal civic centre for the islands, expanding after Indian independence to host civil and defence establishments.

Administration, defence and economy

Port Blair houses key territorial institutions: the civil administration of the union territory, courts and police headquarters, and the Andaman and Nicobar Command — India’s integrated tri-service command that coordinates operations across the island chain and maritime approaches (armed forces). The economy blends government services with tourism, fisheries, small-scale trade and port activity. Local markets reflect a mix of communities and supplies that sustain the island population.

Transport, tourism and services

The town is the main arrival point for visitors and supplies: it contains the principal airport and ferry terminals connecting other inhabited islands. Port Blair serves as the gateway for tourist excursions to nearby attractions such as historic sites, coral-fringed beaches and marine parks. Visitor services, hotels and guided tours are concentrated here, and many trips to outer islands depart from the town's harbours.

Notable facts and distinctions
