The Hussainabad Tower, located in Lucknow, is one of the finest examples of British architecture in India. It was built by the Hussainabad Endowment Trust in 1887, to mark the arrival of Sir George Cooper, the first Lieutenant Governor of the United Province of Awadh. But, now it is popularly known as the Hussainabad Picture Gallery. Satkhanda or the 7-storey watchtower lies opposite to the Imambara. Its construction was, however, stopped when, after completion of the 4th storey the Nawab died in 1840. The portraits, which have recently been restored, give a good insight into the grand costumes and jewelry favored by the Nawabs. The 20 ft square tower rises to a height of 221 ft. Built of gunmetal, the components of the tower were imported from Luigate Hill, London. Principal wheel of the clock is one and a half inches thick and has a diameter of 2 ft, which makes it larger than the Westminister Clock.
