Hazrat Nizamuddin Dargah.

Yes — it's one of Delhi's earliest mosques still in continuous use, built between 1315 and 1325 during the Khalji dynasty, and it sits inside the emotionally charged Hazrat Nizamuddin Dargah precinct. The recent conservation stripped away centuries of paint to reveal the original red sandstone, Quranic inscriptions, and lotus-bud carvings, so you're seeing the building closer to its 14th-century state than visitors could a decade ago. Combine it with the dargah, Amir Khusrau's tomb, and the surrounding food lanes for one of Delhi's most layered outings.

Entry is free — there's no ticket counter or booking system. The mosque sits inside the Hazrat Nizamuddin Dargah precinct, which is also free to enter. You may be offered flowers, chadars, or guided help by vendors near the entrance, but none of that is required for entry. Carry a small amount of cash if you want to make a voluntary donation, and politely decline the rest.

For architecture, go on a weekday morning or late afternoon when crowds are thin and the red sandstone catches warm light. For atmosphere, Thursday evening brings qawwali to the dargah precinct — the mosque becomes part of a larger sensory event of music, incense, and devotional energy, though expect slower movement and packed lanes. Avoid major religious occasions like Urs and Ramadan peak hours unless you specifically want the festival intensity.

Take the Violet Line metro to Jawaharlal Nehru Stadium or Jangpura station, then walk 10 to 15 minutes through Nizamuddin Basti's narrow lanes to the dargah precinct. Alternatively, the Pink Line's Sarai Kale Khan–Nizamuddin station works if you're arriving by train. A taxi or auto-rickshaw can drop you near the lane entrance on Boali Gate Road, but you'll walk the final 200 to 300 meters on foot regardless — no vehicle fits through the basti's old streets.

The mosque alone takes 15 to 20 minutes if you want to study the restored stonework, inscriptions, and lotus-bud arches. But treating it as a standalone stop misses the point — budget 45 to 90 minutes for the full dargah precinct including Amir Khusrau's tomb, the baoli, and the approach lanes. If you add Humayun's Tomb and Sunder Nursery, both walking distance away, make it a half-day.

Look up inside the central chamber where corner squinches turn the square room into the dome — that transition is the most rewarding architectural detail. The lotus-bud carvings on the arches show how early Delhi Sultanate builders worked through Indian craft vocabularies rather than importing a sealed foreign style. At the far ends of the facade, easy-to-miss ewaan-like openings with low jali barriers turn what seems like a simple three-arched front into something more layered.

Cover your head, shoulders, and legs — this applies to both men and women. Remove shoes before entering the mosque and inner shrine areas. Scarves and caps can usually be borrowed or bought for a small amount near the dargah entrance. This is an active place of worship, not a museum, so dress as you would for a religious service rather than a sightseeing stop.

The mosque was commissioned between 1315 and 1325 by Khizr Khan, eldest son of Sultan Alauddin Khalji, beside the khanqah of Sufi saint Hazrat Nizamuddin Auliya — a move that was as much about political proximity to moral authority as it was about piety. Khizr Khan was later killed in a succession struggle after his father's death, and the mosque outlived the prince by seven centuries. Local tradition holds that the structure was originally intended as Nizamuddin Auliya's tomb, but the saint chose burial in the open courtyard instead, fixing the sacred geography that still draws pilgrims today.
