Hoji,
I found many things amazing about the pyramids.
The shear size for a start,
The fitting of the blocks from which they are made.
The internal chambers/ shafts, all made with massive spanning lintel beams etc.
The exactness in which these massive structure have been built, so long ago.
How they were built, why they were built in the first place and course WHO built them.
Amazing stuff.
