Among the many historical monuments within the Qutub Minor complex of Delhi, 15 km from New Delhi Railway Station, stands a tall massive structure which is said to be an ambitious project undertaken by Sultan Aladdin Khilji of Khilji dynasty in 1311. Standing just north of  Qutub Minar what some historians refer to as a vanity project is an unfinished structure commissioned by  Sultan Aladdin Khilji as a victory tower.

Being ruthless and great warrior,  Khilji  won many wars with a powerful army, using skill and tactics. Aladdin Khilji was keen to have a  giant structure built to commemorate his victory over one of his Deccan campaigns and  wanted his name to be etched in history  for his monumental structure that was more spectacular and impressive than his earlier feats.

He planned  to have the new structure built twice the height of Qutub Minar . He already double the size of   Quwwat- Ul- Islam Masjid before 1300 CE,. He further wanted to  increase the size of the enclosures of the  Quwwat-Ul-Islam Masjid by four times its original size to provide a ceremonial entrance gateway on either sides of the mosque.

 He wanted the  new structure - the Alai Minar to match the grand mosque with  increased height. In addition, he was desirous of  a second tower of victory under his name and hence the Alai Minar was initiated. Famous Sufi poet named Amir Khusro, in one of his works named 'Tareekh-i-Alai',  made a reference to  the Sultan's intentions to increase the size of the mosque and the plan to construct the Alai Minar.

The construction came up  to the first floor the work  stopped midway  due to Ala-ud-din Khalji' death  in 1316 AD. Unlike Khiliji, his successors failed to continue the unfinished construction work  because  of changing political situation in and around Delhi. The Khilji rulers were defeated and the Delhi Sultanate  came under the  Tughlaq dynasty. Ala-ud-din Khalji'  grand ambition never never fulfilled as the future is never predictable. The subtle fact is he did complete a grand tower - however  the Qutub Mimar   is being visited by thousands of people  every day.

Alai Minar with  a total height of 24.38 m (80 feet) and a circumference of 77.72 m (255 feet) has an outer wall which is unusually thick - 5.8 m (19 feet)  and is divided into 32 faces of 2.43 m (8 feet) each. There is a central column in the interior where there would a stairway to reach higher level.  The central column itself is 8 m (26 feet) in diameter. The passage was 3 meter wide to allow the construction of stairway. The doorway is on the eastern side of the tower.
