Lucknow, the capital of Uttar Pradesh, extends along the banks of the River Gomti. The city is dotted with remnants of its historic past and became known as a centre for Urdu poetry and courtly diction. Visit the Bara Imambara, built by Nawab Asaf-ud-Daula in 1784, one of the architectural highlights of the era. The central hall is believed to be the largest vaulted chamber in the world. Except in the galleries in the interior, no woodwork has been used in the structure. See the Rumi Darwaza – the colossal, ornate gate which is a replica of the one in Istanbul; Hussainabad Imambara built by Mohammed Ali Shah in 1835. The walls of the mausoleum are decorated with verses in Arabic. Chandeliers, gilded mirrors, colourful stucco, the King’s throne and ornate tazia or replicas of the tombs at Karbala adorn the interior.
