Hazarduari Palace, earlier known as the Bara Kothi, is located in the campus of Kila Nizamat in Murshidabad, in the Indian state of West Bengal. The name of the palace that is Hazarduari means "a palace with a thousand doors". It was built... in the nineteenth century by architect Duncan Macleod, under the reign of Nawab Nazim Humayun Jah of Bengal, Bihar and Orissa (1824–1838). The foundation stone of the palace was laid on August 9, 1829, and that very day the construction work was started. William Cavendish was the then Governor-General. Now, Hazarduari Palace is the most conspicuous building in Murshidabad. In 1985, the palace was handed over to the Archaeological Survey of India for better preservation. Kila Nizamat or Nizamat Kila was the site of the old fort of Murshidabad. It was located on the present site of the Hazarduari Palace, on the banks of the Bhagirathi River. The fort was demolished to build this grand palace. The palace was built and designed under the supervision of Colonel Duncan MacLeod of the Bengal Corps of Engineers. The foundation stone of the palace was laid by Nawab Nazim Humayun Jah of Bengal, Bihar and Orissa (1824–1838) on August 9, 1829, and that very day the construction work was started. The construction was completed in December 1837. The enclosure where the palace is situated is known as Kila Nizamat or Nizamat Kila. The campus except this palace, has in addition the Nizamat Imambara, Wasif Manzil, the Bachhawali Tope, Murshidabad Clock Tower, three mosques out of which one is the Madina Mosque, and the Nawab Bahadur's Institution. Other buildings include residential quarters. It is situated on the east bank of the Bhagirathi River, which flows just beside it. The gap between the Bhagirathi's banks and the palace is just 40 feet (12 m); however, the foundations are laid very deep, which protect the palace. The palace is rectangular in plan (130 meters long and 61 meters broad) and is a good example of Indo-European architecture. The front facade of the palace, which has the grand staircase, faces north. This staircase is perhaps the biggest one in India. The palace has 1000 doors, of which 900 are false, and a total of 114 rooms.
