From Lucknow's historic Residency, place of key events during the 1857 Sepoy Mutiny, to Mahatma Gandhi's birthplace in Porbander, the ASI is also all geared up to hoist the national flag at the sites of 150 of its monuments on the Independence Day, officials said.

"Our national flag would be hoisted at ASI sites spanning the length and breadth of the country in the true spirit of India's diversity and the Azadi ka Amrit Mahotsav. They will be hoisted at Fatehpur Sikri and Agra Fort in our Agra Circle. In Delhi, the tricolour will flutter high at the ruins of Kotla Feroz Shah and Purana Qila," a senior official had earlier told PTI.

It is a UNESCO World Heritage Site, besides Qutub Minar and Humayun's Tomb, in Delhi.
