Lucknow, a large city in northern India, is the capital of the state of Uttar Pradesh. Toward its center is Rumi Darwaza, a Mughal gateway. Nearby, the 18th-century Bara Imambara shrine has a huge arched hall. Upstairs, Bhool Bhulaiya is a maze of narrow tunnels with city views from its upper balconies. Close by, the grand Victorian Husainabad Clock Tower was built as a victory column in 1881.Retaining a feast of British Raj architecture as well as home to two grandiose tombs, Lucknow was the administrative and cultural hub of the Nawabs of Avadh (Oudh). During the period of the weakening of the Mughal Empire, the city rose into prominence as a centre for poetry, music, dance and courtly diction.
