Gurdwara Nanak Piao is situated on Rana Pratap Road in the Shakti Nagar area of New Delhi. The gurdwara was built to commemorate Sri Nanak Dev, the first Sikh Guru. The site where the Delhi Gurdwara Nanak Piao stands was once a garden where the Guru camped during his visit to Delhi in 1505. The people, who came to visit the Guru during his visit, used to present him and his bard Mardana with numerous gifts, which he distributed among the deprived and poor. Infact, the Gurudwara Nanakpiao, in New Delhi, got its name from the habit of Guruji to offer food and water to the hungry and thirsty people. The well from which Guru Nanak served water to the people is still inside the compound of the Gurudwara.
There is an interesting legend associated with the Gurudwara Nanak Piao. It is said that when Guru Nanak came to Delhi, Sultan Sikander Shah Lodi came to know of his visit. He had heard that Guru had performed the miracle of reviving a dead elephant. So, he asked Guru Nanak Dev to revive the one of his dead royal elephants. However, Guru Nanak refused and as a punishment, the ruler ordered his imprisonment. During the time of his incarceration, Delhi suffered a massive earthquake on July 3, 1505. It was assumed that the ill treatment and captivity of the Guru had caused the calamity. Finally, Sikander Shah Lodi conceded and ordered the release of the Guru Nanak.
