Qudsia Bagh is a Mughal-era garden site north of Old Delhi, built by Qudsia Begum, wife of Emperor Muhammad Shah and mother of Ahmad Shah Bahadur. Much of the original garden has disappeared, but surviving gateways and walls still hint at the scale of the 18th-century retreat.
It is a quieter historic stop than the Red Fort or Chandni Chowk. Visit it as part of a northern Old Delhi walk, especially if you are interested in the city's late Mughal history and half-hidden ruins.
