The Festival Hall of Thutmose III (Akh-menu) is an ancient shrine in Luxor (Thebes), Egypt.
It was originally built to celebrate the jubilee (Heb-Sed) of the 18th Dynasty pharaoh Thutmose III, and later became used as part of the annual Opet Festival.
Built at the eastern end of Karnak's main axis, and enclosed in its own walls, this building is little understood and its exact purpose is still unclear.
[2] It consists of three main parts, a suite of rooms dedicated to Sokar to the south-east, a solar complex to the north-east and the festival hall itself, from which the other areas of the building can be reached.
In a small room off of the main hall, there is a room referred to as the Chamber of Ancestors, where a large inscription, the Karnak king list, shows Thutmose III making offerings to his 61 ancestors.
