The only thing in Kom Ombo I'm familiar with is the temple, which I toured when I was visiting Egypt on a cruise along the Nile. The tour I did was fascinating and lasted for a good two hours. This temple stands close to the Nile and looks quite magnificent in the evening as the sun is setting (even if the sunset is over very quickly!).
I was lucky enough to do the tour with a French-speaking guide who was very passionate about his subject. What makes this particular temple special is the fact that it is dedicated to two different gods: Horus, the falcon-headed god, and Sobek, the crocodile god, hence the presence of mummified crocodiles in the temple – sacred crocodiles were kept at the temple and embalmed when they died.
It's worth noting that this is actually the temple in which there are engravings of ancient Egyptian surgical instruments to be seen, some of which are apparently still in use today!
