Southern Tomb 25 at Amarna was intended for the burial of Ay, who later became Pharaoh, after Tutankhamun. The tomb was never finished, and he later buried in the Western Valley of the Valley of the Kings (WV23), in Thebes.
The tomb was only partially carved from the rock, with the first part of the pillared hall only being anything like completed. The tomb contains depictions of Ay receiving rewards from Akhenaten and Nefertiti.
The tomb also contains a version of the Great Hymn to the Aten.
