Founded on 3 April 1917 during the British Raj to house the historical artefacts found in the vicinity of Patna, it is constructed in the style of Mughal and Rajput architecture, and is known locally as the Jadu Ghar. Artefacts from the ancient India era to 1764 have now been transferred to Bihar Museum.
