Hanuman Setu Temple is located on the banks of Gomti River near Lucknow University in Lucknow, Uttar Pradesh. The shrine was early located near the Gomti River ghat but it was shifted due to floods. Neeb Karori Baba consecrated the present structure in 1967. Setu means bridge. There is a bridge near the temple, which faced numerous difficulties during construction. But after offering prayers and puja to Hanuman, the bridge was completed without any incident.
The main murti of Hanuman worshipped in the shrine is in standing posture. He is clad in a yellow dhoti and red kurta. He also has a silver crown. The murti is depicted as showing Sri Ram and Mata Sita in his heart.
Apart from this, there are murtis of Ganesha, Shiva, Goddess Parvati and Neeb Karori Baba in the temple complex.
A unique custom in the temple is giving letters to Hanuman. Devotees make their wish through letters. The ritual was started by Neeb Karori Baba to help devotees who could not travel to the temple. But today even nearby people write letters to Hanuman.
The most important festivals observed here are Hanuman Jayanti, Guru Purnima and annual Bhandara. Tuesdays in the month of Jyeshta month is observed as Bada Mangal here and attracts thousands of devotees.
