I should also add that although I by no means am a religious man (agnostic), Uppsala cathedral always moves me deeply in a way I can't rationally explain. Be it the work put into the building, centuries of prayers, its sheer size, the atmosphere, history, God or a combination of factors, I don't know nor care as long as I get to feel it. Luckily I have family in Uppsala, and thus ample opportunity to visit.
You must be an insomniac. It's got to be 2 in the morning in Sweden.
