Exquisitely patterned. The details are intricate, beautiful and intriguing. There are deep recessed areas here, floating curtains, a wealth of gorgeous subtle colour and darker, brooding areas for contrast. This looks like an aerial view of a series of ornately decorated chambers with fantastic mosaic walls and floors, marvellous embroideries, rich velvet and delicate silk hangings, and swirling spiral staircases to yet further levels.
This is for serious business despite it's beauty. These are council chambers or the rooms of a major organisation, group or movement. Sombre responses to crises, thoughtful consideration for the future and decisions which will affect hundreds or thousands or millions are made here.
I was gonna say this is exqusite in its intricate detail but margali beat me to the punch. I'll just follow with "A long time ago in a galaxy far far away" people met in such lavish, ornate halls to celebrate just about everything.
