Patna Museum is the state museum of the Indian state of Bihar. Started on 3 April 1917 during the British Raj to house the historical artefacts found in the vicinity of Patna, it is in the style of Mughal and Rajput architecture and is known locally as the Jadu Ghar. The artefacts from ancient India era to 1764 have now been transferred to Bihar Museum. The KP Jayaswal Research Institute (KPJRI) which carries out research in the field of history and archaeology also operates out of Patna Museum and was established by the Bihar Government.
