Raised on the foundations of a former small taziakhana , the building has undergone alterations . During the rule of the East India Company , it was repaired in 1807 and 1810 . The original date of construction is still disputed , but Hussaini Dalan in its present form is attributed to Nasrat Jung , who rebuilt the imambara in 1823 . The present flat roof was rebuilt by Nawab Ahsanuallah Bahadur after the earthquake of 1897 , and another verandah was added to the southern side .
