at Aliganj in Lucknow city.

Behind the origin of “Bada Mangal” fair, there are various theoretical stories. One legend propounds that the child of the Nabab Mohammad Ali Shah fell ill and doctors were unable to cure the child. The wife of the Nawab (Begum Rabia) took the child to various places in the hope to get a solution to the child’s health. One day during her searches she met the priest of the Naya Hanuman Mandir at Aliganj in Lucknow city. The priest asked her to leave the child in front of the Hanuman idol in the temple and come back after some time. By the blessings of Lord Hanuman, the child was recovered. The mother could not believe in her own eyes. The wife of the Nawab offered to make the temple. The priest suggested that instead of making a temple, it would be better to arrange a fair here as it would lead to the economic prosperity of the region.
From that time, the tradition of celebrating "Bada Mangal" is followed and it attracts thousands of people. Nowadays this festival has become as the unity symbol among Hindus and Muslims in whole Lucknow city.
