Interestingly, while this monument looks like the minaret of a mosque (and combines elements of Egyptian, Syrian, and Turkish architecture) it was originally a memorial to the commander of the British East India Company, Sir David Ochterlony. Ochterlony was instrumental in the defense of Delhi in 1804 against Marathas and a British victory in the Anglo-Nepalese war.
In 1969, it was re-purposed to serve as a monument for those who died in the Indian independence movement. The current name, Shahid Minar (or Shaheed Minar) means “martyrs’ monument.”
The Shahid Minar dates to 1828 and sits in the north of the Maidan, Kolkata’s central park.
