Gurdwara Nanak Piao marks the garden site where Guru Nanak is traditionally said to have camped during a 1505 visit to Delhi. The name refers to the water he offered to travellers, and the shrine remains an active Sikh place of worship in north Delhi.
Visitors are welcome outside prayer times. Cover your head, remove shoes before entering, and treat the langar hall and prayer space as active religious areas rather than museum rooms.
