If you are into building magnificent structures this is a mod you should check out, it adds about a dozen styles of facade blocks that can be used to create ancient Greek/Roman looking builds. They also would work well for public buildings such a libraries, town halls, courthouses, etc.
     These nodes have no craft recipes, so you have to be either in creative mode or use the giveme command to get them.

Supported mods:
Bakedclay ( All colors of baked clay )
Darkage ( Basalt, Chalk, Gneiss, Marble, Ors, Schist, Serpentine, Shale, Slate )
Nether ( Netherrack )
