Pfortenbuch
During 2004–2005, a joint team from the IFAO (French Institute of Oriental Archaeology, Cairo, Egypt) and the University of Strasbourg explored the chambers of the huge tomb. The official reopening was attended by notable officials from Egypt's Supreme Council of Antiquities and other archaeologists working in the area. Further planned work will concentrate on the cleaning, restoration and conservation of the tomb, which has been engraved with many important scripts, such as Pyramid Texts, the "Book of the Dead" or the Great Netherworld Books (e.g. Amduat, Book of Gates and Book of Caverns.)
