Unisankh's tomb was built within the so-called Unis Cemetery-North West, set between the funerary complexes of Netjerykhet and Unis in Central Saqqara. Together with two adjoining tombs of the viziers Ihy and Iynefert, it forms the core of the so-called Line A. The Tomb of Unisankh was discovered and excavated by James E. Quibell, then the chief inspector at Saqqara in 1908, for the purpose of the sale of its chapel to the Chicago museum. The Tomb built of Tura (or more precisely Maasara) limestone is an example of non-royal, large, multi-roomed mastabas belonging to the highest officials of the late Old Kingdom.
