Shunet El Zebib is a vast mudbrick funerary enclosure from the earliest dynasties of ancient Egypt. It is less polished than the Temple of Seti I, but in some ways more startling: a raw, ancient rectangle of walls standing in the desert after more than 4,000 years.
It is best appreciated with a guide who can explain the early royal cemetery around it. Without context it can look like a ruined fort; with context it becomes one of the stepping stones toward Egypt's later pyramid complexes.
