I was perhaps hasty with my choice of links. If you look at the chapel walls behind the sculpture in this photo, you’ll see it’s definitely lined with marble bricks (yes, lined, the outer wall of the building is red sandstone).
Not every room is marble lined, but some certainly are, as well as the marble pillars, columns, stairs, cornices, etc. I’d recommend a visit if you’re ever over this way 
Interesting. Still, I think marble walls are more traditional in chapels and churches than in living quarters. I’ve been to Buckingham Palace and Versailles, and as far as I remember, the internal walls weren’t stone-clad.
Oh, and I’d love to get to Scotland some day - it’s in my top five places to visit. The closest I’ve ever been is York, and that hardly counts.
If you haven’t been there, Pompeii is well worth the visit, also the bay of Naples is incredibly beautiful.
My favorite from that site is the one that is written near the front door of a residence and sets a curse of Jupiter on “the one defecating here.” In other words Whoever you are, stop pooping in my doorway, jerk!.
and also this bit of Roman wisdom:
The one who buggers a fire burns his penis
No “Hello, Sweetie” ?
The worst part about the grafiti at Pompeii is that most of it is modern. Disgusting, really!
Some of the palaces on the Palatine Hill had interior walls covered with marble. So it wasn’t a sign of poverty, but as it was also expensive and a pain to put up, probably outside of the interior design budget of anyone that wasn’t an Emperor.
It was also associated pretty strongly with public buildings, temples, etc. So a Senator or other private individual building themselves a marble villa might come-off as sacrilegious.
Very interesting, but I’m more than a little dissapointed that there were not photos of the original works.
