In short, all the known forms of ancient architecture might have found their inspiration here, and the general effect was tremendous.
"The palace of the King," said Yva, "whereof we approach the great hall." We entered through mighty metal doors, one of which stood ajar, into a vestibule which from certain indications I gathered had once been a guard, or perhaps an assembly-room.

It was about forty feet deep by a hundred wide.

Thence she led us through a smaller door into the hall itself.

It was a vast place without columns, for there was no roof to support.

The walls of marble or limestone were sculptured like those of Egyptian temples, apparently with battle scenes, though of this I am not sure for I did not go near to them.
