The Qutb Minar was built over the ruins of the Lal Kot, the citadel of
Dhillika. It is usually thought that the tower is named for
Qutb-ud-din Aibak, who began it. It is also possible that it is named after Khwaja
Qutbuddin Bakhtiar Kaki a 13th-century
sufi saint, because Shamsuddin Iltutmish was a devotee of his. The Minar is surrounded by several historically significant monuments of the Qutb complex. Quwwat-ul-Islam Mosque, to the north-east of the Minar was built by Qutub-ud-Din Aibak in A.D. 1199. It is the earliest extant - mosque built by the Delhi Sultans. It consists of a rectangular courtyard enclosed by cloisters, erected with the carved columns and architectural members of 27
Jain and
Hindu temples, which were demolished by Qutub-ud-Din Aibak as recorded in his inscription on the main eastern entrance. Later, a lofty arched screen was erected, and the mosque was enlarged by Shams-ud- Din Itutmish (A.D. 1210–35) and Ala-ud-Din Khalji. The Iron Pillar in the courtyard bears an inscription in Sanskrit in
Brahmi script of fourth century A.D., according to which the pillar was set up as a Vishnudhvaja (standard of god Vishnu) on the hill known as Vishnupada in memory of a mighty king named Chandra. The nearby pillared
cupola known as "Smith's Folly" is a remnant of the tower's 19th century restoration, which included an ill-advised attempt to add some more stories. In 1505,
an earthquake damaged the Qutb Minar; it was repaired by
Sikander Lodi. On 1 September 1803, a
major earthquake caused serious damage. Major Robert Smith of the British Indian Army renovated the tower in 1828 and installed a pillared cupola over the fifth story, creating a sixth. The cupola was taken down in 1848, under instructions from
The Viscount Hardinge, the
Governor General of India. at the time. It was reinstalled at the ground level to the east of Qutb Minar, where it remains. This is known as "Smith's
Folly". It was added to the list of World Heritage Site by UNESCO in 1993. == The Ghurids ==
