My first attempt at using radiosity.
Comment welcome.

The beams through media look very crisp and nice. here are a fex remarks in the
order that would matter most first:
There seems to be too much light from inside to have a balance that would reveal
radiosity well. Could the inside lights be dimmed ? maybe even remove with
radiosity. The scene would contrast more
Some of the colors are too saturated. (srgb? assumed_gamma?)
the reflective elements, show too strong a total reflective amounts. You can use
conserve_energy and albedo keywords to solve that.

A cool scene!
You need area light for the sun. Radiosity seems okay, perhaps a bit bright for
such small window area.
As said by Mr., colors and textures aren't very realistic - colors are extreme
and the surfaces are too clean. The metal finishes use a diffuse value like 0.6,
which is much to high. Good values are 0.05 to 0.2 together with reflection
values like reflection {0.3 metallic} or higher.
Keep up the good work,
Norbert Kern

Nice work on the stained glass windows and the script-patterns on the
pillars!
How did you make the spiral things on the lamps?

I don't know, but it could be a sphere_sweep, probably stretched in one
direction.

Quite some times I wished PovRay had a prism or polygon sweep feature.

It's a bunch of cylinders:
#for(Count_1,0,410)
cylinder{<0,0,-0.1-Count_1/410>,<0,0,0.1+Count_1/410>,0.2
translate<Count_1/80,2,0> rotate<0,0,1.5*Count_1> }
#end

Thanks for the comments.
I have reduced the gamma, gray_threshold and brightness.
The steel-work is now a darker pigment and less reflective.
Getting there slowly, this radiosity thing is complicated :-)

The Stained glass windows and pillar decorations are lifted from photos
on the internet :-)
