A five-storey building promoted by former BSP MP Dawood Ahmed in Lucknow was razed to the ground yesterday. The action was taken after the Archaeological Survey of India (ASI) raised the red flag, citing its proximity to the protected site of the Residency in Lucknow. The Residency is a group of buildings that served as home for the British Resident General who was a representative in the court of the Nawab. Built in the 18th century, the Residency was at the centre of the Siege of Lucknow during the first war of Independence.
