Among the six rulers of the Khilji dynasty, Allauddin Khilji is the most well  known who extended his dominion down southern India too, and created the third city of Delhi, Siri. The Saljuqian influences from West Asia are the most remarkable feature in the buildings from this period. A large reservoir called Hauz Khas was another accomplishment of city of Siri. A madrasa (college) was also created here by later rulers. Hauz Khas today is a complex against the ruins of the ancient SIRI fort.
