In the centre of Stockholm is the island of Gamla Stan (actually an area consisting of several islands, for the pedants out there), the old town. While I was walking around I happened upon the Nobel Museum, which was having an open day. So I took a look inside. I guess the biggest surprise (for me at least, I'm sure you all know this) was to find that Alfred Nobel made his money from the manufacture of explosives.
