One of the finest examples of Indo Islamic heritage, Qutub Minar is a popular historic site and a sought-after tourist attraction in Delhi. Built by the Mughal emperor Qutub-ud-Din Aibak in 1193, the 240 feet tall tower is the tallest brick minaret in the world. Apart from the minaret, the Qutub complex also features several other architectural marvels that make the complex a UNESCO World Heritage Site.
