Vertical elements in churches main function it to have you look up, hopefully towards where we perceive heaven to be. This is a reflection of our natural tendencies. I have yet to find a culture where when they are happy they look down, or when in a defeated stance look up.
Each stone you see weighs 50 to 100 pounds. Estimates say they moved over 125,000 cubic feet of rock. Some fathers and grown sons hauled as many as 70-80 loads of stone to help raise this from the ground. By the way...no automatic lifts or power tools!
