Pillars at the Karnak temple - Luxor, Egypt.
This temple in Luxor is amazing! There is around 134 of these pillars that have hieroglyphs carved into them. They say that they built these pillars by placing the first piece into place then surrounding it with sand to move the second piece into place on top and so on, untill they built the pillar up to 70 feet high. Then carving the pillars on the way down while removing the sand.
