Alai Minar

Alai Minar, the abandoned tower that if completed was to be twice tall as Qutab Minar!

Ala-ud-din Khilji wanted to make a memorial tower, twice as tall as the Qutab Minar. He made the master plan and set the foundation. But the construction could not go more than a floor at 24.5 meters by the time of his death.
