Built in the early 13th century a few kilometres south of Delhi, the red sandstone tower of Qutb Minar is 72.5 m high, tapering from 2.75 m in diameter at its peak to 14.32 m at its base, and alternating angular and rounded flutings. 

Qutab Minar is a soaring, 73 m-high tower of victory, built in 1193 by Qutab-ud-din Aibak immediately after the defeat of Delhi's last Hindu kingdom. The tower has five distinct storeys, each marked by a projecting balcony and tapers from a 15 m diameter at the base to just 2.5 m at the top. The first three storeys are made of red sandstone; the fourth and fifth storeys are of marble and sandstone.

At the foot of the tower is the Quwwat-ul-Islam Mosque, the first mosque to be built in India. An inscription over its eastern gate provocatively informs that it was built with material obtained from demolishing '27 Hindu temples'.

A 7 m-high iron pillar stands in the courtyard of the mosque. It is said that if you can encircle it with your hands while standing with your back to it your wish will be fulfilled.

The origins of Qutab Minar are shrouded in controversy. Some believe it was erected as a tower of victory to signify the beginning of the Muslim rule in India. Others say it served as a minaret to the muezzins to call the faithful to prayer.
