Viper Island is a small island located in the Andaman Islands of India. It holds historical significance and is situated near Port Blair, the capital of the Andaman and Nicobar Islands.

During the British colonial era, Viper Island was used as a place of penal settlement where convicts and political prisoners were incarcerated. The island is infamous for its Cellular Jail, a colonial-era prison where Indian freedom fighters were imprisoned and subjected to harsh conditions.

The Cellular Jail was initially constructed to confine freedom fighters and revolutionaries during India's struggle for independence from British rule. It was a symbol of the British government's oppression and a place where many Indian patriots endured immense suffering and sacrifice.

Today, Viper Island is a tourist attraction, drawing visitors interested in learning about India's struggle for freedom and the historical context of the Cellular Jail. Tourists can visit the ruins of the Cellular Jail and witness a crucial part of India's independence movement. The island also offers scenic views and is accessible by boat from Port Blair.
