>The Romans didn't build the piramids, the
Egyptians did.  They were indeed dry-stacked, but not like a Vermont stone
wall, because the piramids haven't fallen down yet.<

Also, unlike Vermont, Egypt has almost no precipitation. The state of
preservation of Pharaohnic stone structures is likely due to the dry
climate and no water penetrating and freezing.
