Qutub Minar

Qutub Minar, also spelled as Qutb Minar, is a 73m tall minaret located in a large compound, the Qutb complex, in Delhi. Construction of Qutub Minar started in 1199. Initially one storey was completed, and later more were added. The Quwwat-ul-Islam mosque was also built at the same time in the compound, but nowadays only ruins of it are left. The Qutub complex includes a number of other structures, such as the Alai Minar and the Alauddin Khilji tomb and madrasa. Qutub Minar has been a UNESCO world heritage site since 1993.
