Qutub Minar is the pride of Delhi. The tall minaret was constructed in 1192 by Qutab-ud-din Aibak , and later completed by his successor Iltutmish. The soaring conical tower is an exquisite example of Indo-Islamic Afghan architecture. Qutub Minar is a World Heritage Site and has survived the ravages of time impressively. The Minar of Delhi is surrounded by a lush green garden, which is an ideal leisurely place for visitors. Qutab Minar is the favourite destination of tourists. It is India's most visited monument attracting around 3.9 million visitors every year.
