Ala'i Darwaza (Urdu: علاء دروازه, lit. 'Gate of Alauddin') is the southern gateway of the Quwwat-ul-Islam Mosque in Qutb complex, Mehrauli, Delhi, India. Built by Sultan Alauddin Khilji in 1311 and made of red sandstone, it is a square domed gatehouse with arched entrances and houses a single chamber.
It has a special significance in Indo-Islamic architecture as the first Indian monument to be built using Islamic methods of construction and ornamentation and is a World Heritage Site.[1]
