In 1199, Qutub-ud-Din raised the Qutub Minar either as a victory tower or as a minaret to the adjacent mosque. From a base of 14.32m it tapers to 2.75m at a height of 72.5m and a valid reason why it took two decades to complete this monument. Its a red sandstone tower covered with beautiful and striking carvings and is inscribed with verses from the holy Quran. Qutub Minar is still the highest stone tower in India as well as one of the finest Islamic structures ever raised and Delhi's recognised landmark. The sultan's successor and son-in-law, Iltutmish, completed it.

In 1303, Ala-ud-Din established the second city of Delhi, called Siri, of which nothing remains but the embattlements. He also had dug a vast reservoir, Hauz Khas, to supply water to his city. Contemporary historians describe the Delhi of that time as being the "envy of Baghdad, the rival of Cairo and equal to Constantinople".

For the sake of convenience, tourists visiting the Qutub Complex could also see the Tomb of Adham Khan and Zafar Mahal in Mehrauli and the Tomb of Jamali-Kamali behind the Qutub Minar. These however, belong to a later date.

The Damage & Restoration
From the Nagari and Persian inscriptions on the minar, it appears that it was damaged twice by lightning, in 1326 and 1368. The first damage occurred during Muhammed Tughluq's reign (1325-51), and was repaired by him apparently in 1332. The second damage was attended by Feroze Tughluq (1351-88). Later in 1503, Sikandar Lodi (1489-1517) also carried out some restoration in the upper storeys.

Originally the minar had only four storeys, faced with red and buff sandstone. The uppermost storey, which was damaged in 1368 during Feroze Tughluq's reign, was replaced by him by two storeys, making free use of marble but leaving the lower portion of the fourth storey built with sandstone in its original condition.

The original three storeys are each laid on a different plan, the lowest with alternate angular and circular flutings, the second with round ones and the third with angular ones only, with the same alignment of flutings, however, being carried through them all.

Its projecting balconies with stalactite pendentive type of brackets and inscriptional decorative bands on different storeys heighten its decorative effect. It has a diameter of 14.32 m at the base and about 2.75 m on the top. With a height of 72.5 m and 379 steps, it is the highest stone tower in India and a perfect example of minar known to exist anywhere.

The Legend Of The Qutub
There exists a tradition that the Qutub-Minar was built by Prithviraj, the last Chauhan king of Delhi, for enabling his daughter to behold the sacred river Yamuna, from its top as part of her daily worship.

A Landmark In Islamic Architecture
The Minar's entire architecture, however, bespeaks an Islamic origin, with two of its prototypes in brick still existing at Ghazni, although Hindu craftsmen were certainly employed for its construction, as is evident also from certain 'Devanagari' inscriptions on its surface. Sometimes sculptured stones from temples have been found utilised in it.

Originally, it was surmounted by a cupola, which fell down during an earthquake and was replaced early in the 19th century with a new cupola in the late Mughal style, by one Major Smith. It looked, however, so incongruous that it was brought down in 1848, and may now be seen on the lawns to the south east of the minar.

A Complex Of Astounding Monuments

Foremost Ensample Of Islamic Architecture
Alai Darwaza is the first building employing wholly the Islamic principles of accurate construction and geometric ornamentation and also betrays certain 'Saljuqian' characteristics, which had influenced the Khalji architecture. Important among these characteristics are wide and bulging dome with a central knob, pointed horse-shoe-shaped arches and squinches and lotus-bud fringes of the arches.

The celebrated gateway, built of red sandstone, is 17.2m squares with arched openings on all sides, and is surmounted by a wide but shallow dome on an octagonal base achieved through squinches with concentric series of arches. The northern arch is semicircular, while others have a pointed horseshoe shape, with radiating voussoirs laid on the principle of true arch.

The underside of the arches is fringed with lotus-bud embellishment, not merely in the openings, but also in the perforated side-windows. Its excellent proportions, profuse geometrical carvings on the interior, inscriptional bands of white marble in 'Naskh' characters and other decorative details in red stone make it a very pleasing structure. It has been rightly described as "one of the most treasured gems of Islamic architecture".

The Tomb Of Iltutmish
The tomb of Shamsu'd-Din Iltutmish, son-in-law and successor of Qutub-ud-Din Aibak, lies to the northwest of the Quwwatu'l Islam mosque. It was built in about 1235 by Iltutmish himself, only five years after the construction of Sultan Ghari's tomb. Yet, it is quite different from the latter and illustrates that phase in the development of Indo-Islamic architecture, when the builder had ceased to depend for material on the demolition of temples, although the arches and semi-domes below the squinches were still laid in the indigenous corbelled fashion.

A Unique Tomb Structure
Its tomb-chamber with a cenotaph in its centre, internally nearly 9m-sq and faced with red sandstone, was certainly intended to be covered with a dome, as is clear from the squinches, which appear for the first time in this building. It is believed that the original dome had fallen and was replaced by Feroze Shah Tughluq, but even this did not survive.

The interior on the west is occupied by three 'minhrabs' or prayer niches, the central one higher and ornamented with marble, to serve as a place for prayers, while the other sides are pierced by arched entrances.

The tomb is plain on the outside, but is profusely carved on the entrances and in the interior with inscriptions in 'Kufi' and 'Naskh' characters with geometrical and arabesque patterns in saracenic tradition, although several motifs among its carvings are reminiscent of Hindu decoration. To this class belong wheel, bell-and-chain, tassel, lotus and diamond. In view of its lavish ornamentation, Fergusson described it as " one of the richest examples of Hindu art applied to Muhammadan purposes".

Ala-Ud-Din's Tomb And College
To the southwest of the Quwwatu'l-Islam mosque lie some rooms and halls in ruins making an L-shaped block. They are believed to represent Ala-ud-Din's tomb and college or madrasa, which was started by him to impart instructions in Islamic theology and scriptures.

The central room in the southern wing was perhaps his tomb. The conception of a combined college and tomb appears here in India for the first time and is perhaps inspired by 'Suljuqian' traditions.
