Medieval Delhi Landmark
Siri Fort was established in the early 14th century by Alauddin Khalji. He founded Siri as the second city of Delhi to strengthen his kingdom and improve its defenses.
Siri became the administrative and political center of the Delhi Sultanate. Important government activities, military planning, and royal affairs were conducted within the fortified city.
After the Khalji dynasty, the importance of Siri gradually declined as later rulers established new cities and capitals in different parts of Delhi.
During Alauddin Khalji’s reign, the Delhi Sultanate faced repeated threats from Mongol forces. Siri Fort was constructed as a heavily fortified military stronghold to protect the capital from these invasions.
The city included palaces, military structures, defensive walls, and public buildings. Contemporary accounts describe Siri as a prosperous and strategically planned urban center.
Although much of the original city has disappeared, sections of the fort walls and ruins still survive, preserving the memory of one of medieval Delhi’s most important settlements.
