Qutub Minar

One of the most visited tourist spot of Delhi, Qutub Minar was built in 1199 by Qutub-ud-Din. The sultan's successor and son-in-law, Iltutmish, completed it. The purpose of building this beautiful monument is not very clear as some believe that it was built as a tower of victory to signify the beginning of the Muslim rule in India, while others say it served as a minaret to the adjoining mosque and was used by the muezzins to call the faithful to prayer. It is 72.5 metres high and one has to climb 379 steps to get to the top.The diameter of the base is 14.3 metres while the top floor measures 2.7 metres in diameter.

Qutub Minar is still the highest stone tower as well as one of the finest Islamic structures ever raised in India. The main mosque comprises an inner and outer courtyard, of which the inner one is surrounded by an exquisite collonade, the pillars of which the inner one is surrounded by an exquisite collonade, the pillars of which are made of richly decorated shafts.

History
Qutab-ud-din Aibak, the first Muslim ruler of Delhi, commenced the construction of the Qutub Minar in A.D. 1193, but could only complete its basement. His successor, Iltutmush, added three more stories, and in 1368, Firoz Shah Tuglak constructed the fifth and the last storey. The development of architectural styles from Aibak to Tuglak are quite evident in the minar.

Iron Pillar
Close to the mosque is one of Delhi's most curious structures the Iron Pillar. Dating back to 4th century A.D., the pillar bears an inscription which states that it was erected as a flagstaff in honour of the Hindu god, Vishnu, and in the memory of the Gupta King Chandragupta II(375-413). How the pillar moved to its present location remains a mystery. The pillar also highlights ancient India's achievements in metallurgy. The pillar is made of 98 per cent wrought iron and has stood 1,600 years without rusting or decomposing.
