Old depiction of the national shrines
This detail of a wooden label shows the Upper Egyptian temple in the top row with two flags and the standard of the goddess Neith the patroness of Lower Egypt. This indicates a union between gods (and maybe also of royalties) of the two nations confirmed by this sign standing in the center of a fenced courtyard with an elephant-like house.
In the second row a bird (possibly meaning the town of Buto in the Delta) sits upon the roof of the temple of Lower Egypt which has a high extension at its left side, probably around an inner yard. Most likely this holy house was made of the basic material - reed.
