This rather lovely fireplace is obviously not new, nor in use any more, but it mostly amuses me because it's in one of the bathrooms at the Courtauld Institute in London. You may make an old building (1776) into a modern university college, but if it's listed (as this is), you don't quite get to wipe out the traces of the old.
When I say bathroom, btw, I mean loo. Even my granny's house didn't have a fireplace in the actual loo with you. Strangely unnerving.
