Some of that graffiti had me laughing out loud. Gogonzola imposter? It really makes you wonder. Was it a very old building? In older buildings, maybe a fireplace in every room because that is how it used to be heated? I am basing thison my reading of Victorian novels, so it is just speculation.

It did not look old to me, though fireplaces upstairs is an 'old thing'. Without the information textual content.. it would have been a bit crap!
It is indeed a mystery then ... why so many fireplaces? Ha! Peculiar.
