This is arguable. I tend to think that architecture has as much, or even more, implications on geographic/historic location than the textures you actually use. Of course, if you plant a couple of pyramids and make a hieroglyphed tomb entrance, then as you say "oh hi ancient Egypt".
But, if you use the textures on a shape that has nothing in common with ancient Egypt, then I do'nt think it automatically implies it. For instance, take a look at this item I'm working on. Maybe you'll think differently, but to me it certainly does not scream "ancient egypt", although the textures are 100% egypt/. materials.
