A popular UNESCO world heritage site in the Mehrauli area of Delhi, Qutub Minar is a 73-meter tall minaret made up of bricks. Its construction, dating back to 1192, was started by Qutub-Ud-Din-Aibak who had founded the Delhi Sultanate. Inspired by the Minaret of Jam in Afghanistan, the Qutub Minar was a source of inspiration for many minarets built after it like the Chand Minar in Daulatabad, Maharashtra.
