Qutub Minar was constructed in 1192 by Qutab-ud-din Aibak, by the founder of Slave Dynasty and later completed by his son-in-law and successor Iltutmish. The Qutub Minar is the tallest brick minaret in the world. Built exclusively in red brick and sandstone this minaret in Delhi is an exquisite example of Indo-Islamic Afghan architecture.
Qutub Minar at Delhi is a 5 storied tower. Each tower of the famous Qutub Minar has unique designs. It was hit by lightening twice. Due to this hazard, there was major damage in the structure. But during the reign of Muhammad-bin-Tughlaq, the king repaired the ensuing damage. Again during the reign of Emperor Feroze Shah Tughlaq, when the top most storey of the Qutub Minar was destroyed, the king repaired the floor and elevated the Qutub Minar to another level.
Inspired by the Minaret of Jam in Afghanistan the Qutub Minar is an interesting mix of architectural styles. The base of the Qutub Minar at Delhi measures 14.32 meters and the top of the structure measures 2.75 meters. The first 3 stories of the Qutub Minar has different designs. While the base has alternate angular and circular flutings, the second one is round. The third storey of the Qutub Minar has only angular flutings. The balconies projecting out of the Delhi Qutub Minar heightens the beauty of the Minar.
