With a steel pole that looks like it's already rusting, I can't imagine it lasting 1000 years, and good luck putting it back in the same position if you replace the pole! I don't think many buildings would show up, if any. I once took a 10 second pinhole camera exposure of a busy playground, and there's no sign of the children in the image at all. One kid standing still for one second would be like a building that lasts a century for this image, but they weren't visible because of the other 90% of the time.
