Cairo's famous museum of antiquities focuses on Egypt's national past. After the glory days of the Old, Middle, and New Kingdoms (finds from the tomb of Tutanchamun), there is comparatively little attention for the Libyan, Nubian, and Assyrian periods. There's quite a bit on the Twenty-Sixth Dynasty, only a half room about the Achaemenid age, and again a bit more about the Ptolemies.
Photography is forbidden. There are some books for sale with photos of the inevitable doctor Zahi Hawass, though.
This museum was visited in 2008.
