Answer:
can't remeber, though i have learned about them.
Explanation:
As I recall it was rolled-steel girders riveted together, probably from shipbuilding, together with steam-powered winches and an abundance of cheap steel. As opposed to European cathedrals erected with animal-powered winches and with more expensive forged iron bracing (one of the big cathedrals has a kind or iron corset to keep the walls from bursting outwards).
As many as 3000-3500 Christians were executed under the authority of Imperial edicts.
