The temples of ancient Egypt include some of the largest religious monuments the world has ever known and certainly some of the most impressive. As dignified houses for the Gods, temples such as the temple of Amun at Karnak are massive structures. The stone for these structures came from nearby quarries and were usually sandstone or granite. Because the building was done without mortar, each stone was cut with precision so they fit together perfectly.With nothing but the weight of the stone as a means of support, the temples were based upon perpendicular structures. The columns for the temples were therefore cut into sections and each section was placed on top of the other until the desired height was reached.
