This Gurdwara was built at the site where Guru Nanak Dev camped, in the garden when he visited Delhi in 1505 during the reign of Sultan Sikander Shah Lodhi. It is situated on Rana Pratap Road (also known as Grand Trunk Road or GT Road).
Besides this, he used to offer food and water to the hungry and thirsty, hence the name of the shrine. The word "Piao" mean to "offer liquid to drink" and refers to the offering of water to all the thirsty who visited this shrine.
