Alai Darwaza
India's first true dome rises here — built in 1311 when a sultan imported Islamic construction methods to the subcontinent for the first time.

Alauddin Khalji planned four gates for the Quwwat-ul-Islam Mosque; only this one was finished before he died in 1316. In that single structure he introduced two firsts to India: the true dome (47 feet high) and bold red sandstone contrasted with white marble inlay — a combination that defined Indo-Islamic building for centuries. He also drew on stone openwork net screens long established in Indian temples and brought them into an Islamic gateway, substituting for the polychrome tilework common in Persia and Central Asia.
What to look for
- The shallow dome — walls 11 feet thick reveal how cautiously the builders treated unfamiliar technology; the dome only reads clearly from a distance or above
- Pointed arches that pinch into a mild horseshoe curve at the base, their inner edges lined with 'spearhead' projections thought to represent lotus buds
- Stone net screens set into the exterior — a craft long established in Indian temples, repurposed here for an Islamic gateway
Southern gate of the Qutb Complex, Mehrauli — the same walled site as the Qutb Minar and the Iron Pillar; UNESCO World Heritage status since 1993.
