All I can say is that I would not mind to have a house in that part of the world and live there full time or at least have an ability to visit it many times each year. You probably know many places like that, this is one of them. But to be specific to this photo, you have to tell us what it is and where it is.
Saturday Update: Great participation on this one, you guys rock! Good suggestions on where it is, but artandkitchen got it right, it is Carmel Mission Basilica in Carmel (California)!
