Library loft at Fonthill Castle, Doylestown, (USA) Not your typical big house library--looks like something out of "Harry Potter"-- Charming, cluttered and cozy with an authentic "collected over time" look!
I love this stunning library at Trinity College in Dublin. I've strolled through it many times during my trips to Dublin. The Long Room a the Old Library. If you ever get to Dublin, don't miss this jaw dropping piece of architecture and history.
