Alai Darwaza
The 1311 CE gateway on the southern side of the Quwwat-ul-Islam Mosque, built by Delhi Sultan Alauddin Khilji — the first major example of true Islamic structural technique in Indian architecture, using true arches on radiating voussoirs (rather than the corbelled false arches of the earlier Mamluk mosque) and the first dome built on scientific principles in Indian masonry. The red sandstone and white marble construction, inlaid Kufic calligraphy and lotus-bud fringe arches set the template for subsequent Khalji, Tughlaq and Lodi architectural idioms — the Alai Darwaza is the stylistic pivot between the imported Central Asian idiom and the mature Indo-Islamic style. Part of the UNESCO Qutb Minar and its Monuments inscription 1993.

- PatronageAmroha
The Alai Darwaza was completed in 1311, six years after the Mongol armies were broken at Amroha and in the middle of the Deccan campaigns that were funding Delhi. Alauddin's building — the gateway, the unfinished Alai Minar, the Hauz-i-Alai and Siri — is what a sultanate does with the money and the security that come from winning on two fronts at once.
- Site withinDelhi
Alai Darwaza lies within Delhi — the two sites sit about 10 km apart, well inside the city's historical boundary and part of the same urban or peri-urban landscape. Alai Darwaza is one of the specific sites that give Delhi its layered character, and reads differently when seen as a stop within the larger city rather than as an isolated monument on an open map. The surrounding neighbourhoods, roads and other heritage ensembles belong to the same single urban fabric.
- Built byAlauddin Khilji
Alauddin Khilji built the Alai Darwaza in 1311 as the southern entrance to the Alai extension of the Quwwat-ul-Islam mosque, with four gateways (only the southern one survived) each with a true arch and a dome on squinches — the first fully developed Indo-Islamic entrance in India. Red sandstone with white marble inlay, horseshoe arches, and a lotus-bud fringe on the arch soffit, the Alai Darwaza introduces the architectural vocabulary later Mughal gates would elaborate.
- Site adjacencyQutb Minar
The Alai Darwaza stands immediately south of the Qutb Minar inside the Qutb complex — Alauddin Khilji's 1311 Khilji-period gateway framing the Mamluk Qutb Minar across the Quwwat-ul-Islam mosque courtyard, with the unfinished Alai Minar to the north of the minaret. The Khilji buildings together frame the central Mamluk ensemble of the complex.
