What does it look like? Memory Beta is only yea helpful. I seem to remember it described as an inverted pyramid structure, high up above the historic Place de la Concorde with the Champs Elysee below running though it, straddling up high by supporting beams that lead to the palais above the Place below. Are there four beams at each corner or four altogether? Is it an inverted pyramid (maybe akin the the shot of Starfleet HQ in San Francisco in TVH, or a cylindrical structure like the buildings in the background shots of Paris in TNG? What constitutes “troisième Empire” architecture? What did it look like, and when was France's Third Empire conquering "lesser" peoples once again? Did they conquer Colonel Green's people? Khan’s? Remnants of the E-Con? What about it says it’s a “palais,” and not an Executive Office Building? Also, if it's a combined White House and Capitol Building....for an interstellar civilization of a trillion+ beings from a 150+ member worlds and thousands of countless colonies, planets, moons, bases, stations, ships, et al.....shouldn't it be bigger?
