Did you get the Giggle Bell from Peeboo's dream? If not, go back to his dream and fully explore the upper left side of it!
If so, re-enter Athena's dream and go North from the sheep - equip the giggle bell and pass the trees, you'll find El Cairo key there. With it you'll be able to open the church gate in El Cairo and gain access to the Pharoah!
