The Begumpur Mosque is a 14th-century Tughlaq-era mosque in South Delhi, one of the best-preserved mosque complexes from the Delhi Sultanate period. Built by Firuz Shah Tughlaq's prime minister Khan-i-Jahan Tilangani around 1370, it follows the large congregational mosque form with a central courtyard, arcaded colonnades, and a massive prayer hall. Its imposing scale and austere grey stone give it a fortress-like quality typical of Tughlaq architecture.
The mosque lies inside the Jahapanah historic urban zone near Begumpur village, close to Hauz Khas. It is rarely visited despite being one of the most architecturally significant mosques in Delhi, which makes it all the more rewarding to seek out. The Archaeological Survey of India maintains the site; entry is free.
