Alauddin Khalji (r. 1296–1316) undertook significant construction in Delhi, including the building of the Siri Fort — a major defensive enclosure — and grand palace structures (referred to in chronicles as the Hazar Satoon or Thousand-Pillared Palace). These works reflected his desire to secure and monumentalise the capital, providing defensive strength and courtly grandeur. The ruins and archaeological traces in the area correspond to the extensive public and military architecture financed during his reign.
