So I looked in "Porter and Moss" and found a reference to an article that I had scanned some years ago but never read. It was in French, but with a little assistance from an online translation app I produced a more-or-less readable English language version. I have prepared it as a pdf document (available on request). But I here extract some plans and pictures of the temple of Amenhotep, son of Hapu.
Is this deep pit the one immediately in front of Pharoahs Hotel? I will have to take some more precise measurements. But looking at GoogleEarth I think that it must be.
