Imambara, also known as the Nizamat Imambara, is the masterly creation of Nawab Nazim Mansoor Ali Khan Feradun Jah, the heir of Nawab Nazim Humayun Jah, his father in Murshidabad, West Bengal. The mosque was constructed in 1847 following the infernos of 1842 and 1846 as a result of which the Imambara made of wood constructed by Nawab Siraj ud-Daulah was destroyed.
