It is situated near the Bara Imambara and on the connecting road stands an imposing gateway known as Rumi Darwaza. The building is also known as the Palace of Lights because of its decorations and chandeliers during special festivals, like Muharram.
The chandeliers used to decorate the interior of this building were brought from Belgium. Also housed within the building, is the crown of Muhammad Ali Shah and ceremonial tazias. Thousands of labourers worked on the project to gain famine relief.
It has a gilded dome and several turrets and minarets. The tombs of Muhammad Ali Shah and other members of his family are inside the imambara. This includes two replicas of the Taj Mahal, built as the tombs of Muhammad Ali Shah’s daughter and her husband. The walls are decorated with Arabic calligraphy.
Water supply for the fountains and the water bodies inside the imambara came directly from the Gomti River.
