A 73 meter tall, 14.3 meters base diameter Qutub Minar is forms in the Mehruali Area of Dehli India. The UNESCO world heritage site tilts just over 65 cm from the vertical contains spiral staircase of 379 steps. The five storeys tall tapering tower design have been based on the Minaret of Jam, in Afghanistan. The Qutub Minar is a minaret which laid the foundation of Minar were started by Qutub ud Din Aibek around in 1192, however his son in law Shams ud din Iltutmish finish the Minar in 1220. The minar stood stand another 149 years, after massive lightning strike damaged the top storey, which were replaced by Firoz Shah Tughlaq in 1369 and added one more storey. Another Muslim ruler Sher Shah Suri also added an entrance to this tower while he was ruling and Humayun was at an exile. Moreover, several inscriptions in Parso-Arabic and Nagari characters in different sections of the Qutab Minar reveal the history of its construction, and the later restorations and repairs by Firoz Shah Tughluq (1351–89) and Sikandar Lodi in 1489–1517). The Qutub Minar name is actually derived from the Sufi saint Qutbuddin Bakhtiar Kaki whom Qutab Ud-Din-Aibak revered. On 1 September 1803, a massive earthquake caused serious damage to Qutub Minar. Major Robert Smith of the British Indian Army renewed the tower in 1828 and installed a pillared cupola over the fifth story, thus creating a sixth.
The tower was built to celebrate Muslim dominance in Delhi after the defeat of Delhi’s last Hindu ruler. The Qutub Minar is the highest tower in India.

The general public was allowed to go upstairs of minaret, but unluckily a chaos was happened in 1981, when internal staircase lighting failed, which in results of massive stampeded towards the exit and 45 people were killed in crush and few injured. Since then Qutub Minaret has been closed for public.

Moreover Ala'i Minar which stands to the north of Qutub-Minar, was commenced by Muslim ruler Alau'd-Din Khalji, with the intention of making it twice the size of earlier Minar. He could complete only the first storey which now has an extant height of 25 m. Ala'i-Darwaza, the southern gateway of the Quwwat-ul-Islam mosque was constructed by Alau'd-Din Khalji in 1311 as recorded in the inscriptions engraved on it. This is the first building employing Islamic principles of construction and ornamentation.
