Alai Minar, Delhi

About Alai Minar

Alai Minar, located in the Mehrauli area of Delhi within the Qutub Minar complex, is a partially completed tower commissioned by Sultan Ala‑ud‑din Khilji in the early 14th century (c. 1311–1316). Planned as a victory tower twice the height of Qutub Minar, construction stopped after the Sultan’s death, leaving only the first storey standing at 24.5 metres. The tower spans the northeastern section of the complex and demonstrates the architectural ambition of the Delhi Sultanate. Its design showcases Indo-Islamic influences, early rubble masonry techniques, and careful scale planning, making it an important site for archaeology, history, and tourism.

Architecture of Alai Minar

The Alai Minar is a unique example of the architectural vision of the Delhi Sultanate, which combined functional structural engineering with symbolic grandeur. Begun during the reign of Sultan Alauddin Khilji (1296–1316) of the Khilji dynasty, the minaret was intended to be equal to or even taller than the nearby Qutub Minar, but construction was halted after Khilji's death. The surviving minaret stands approximately 24.38–24.5 meters tall and is constructed of reinforced stone masonry held together by lime mortar, reflecting the construction techniques of the time. In contrast to the decorative sandstone and marble of the Qutub Minar, the Alai Minar's unfinished surface reveals its engineering structure and weight-bearing capacity. Its large base, with a circumference of approximately 77.7 metres, reflects the Sultan's grandeur and desire for structural stability.
