El Kab is one of the places along the Nile used to quarry stone for many of the temples.
It is also the home of the tomb of Nekhbet, who I believe was one of the unifiers of Upper and Lower Kingdoms of Egypt.
We sailed on the Edfu, home of the temple of the god Horus, the falcon headed god. The temple is impressive just from the size of the first pylon alone,
Horus was the son of the god Isis and Osiris.
Perhaps this can give you an idea of scale.
