The coolest room I've ever seen - George Lucas' private library on the ranch. This doesn't even do it justice, frankly. From: http://flavorwire.com/261320/20-beautiful-private-and-personal-libraries?all=1
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.
