The Khalifa House Museum is an ethnographic museum, located opposite the tomb of Muhammad Ahmad in the city of Omdurman in Sudan. Towards the end of the 19-th century, it was the residence of the successor of the Mahdi, Khalifa Abdallahi ibn Muhammad and the headquarters of the administration of the Mahdi State. The House was converted into a museum in 1928 during the Anglo-Egyptian condominium.
