Who Planned the City of Delhi?

No single architect is definitively credited. Two major phases:

1. Shahjahanabad (Old Delhi, 1639–1648)

Built by Mughal Emperor Shah Jahan. Master planners likely included Ustad Ahmad Lahauri (chief architect of Taj Mahal) and Ustad Hamid. Grid layout, Red Fort, Jama Masjid, Chandni Chowk.

2. New Delhi (1911–1931)

Designed by Sir Edwin Lutyens & Sir Herbert Baker for the British Raj. Grand imperial geometry: Rajpath, Rashtrapati Bhavan, Secretariat, India Gate. Lutyens' Delhi remains the governmental core.

Conclusion

Delhi's urban fabric is a palimpsest: medieval sultanates, Mughal capital, British imperial city, post-independence expansion. No one "planned Delhi"—many did, across centuries.
