What my walk has taught me is this: the first way that Göteborg differs from other Swedish cities I've visited is topology. This is a city built on hills, lots of them. I spent most of time climbing and descending the steps that comprise the various pedestrian ways through the neighborhood. It paid off in the end, though: our cool building turned out to be Carlanderska, a private hospital from the late 20s.
Incidentally, I'm not the only one to have an unintended stroll around Göteborg today, although I very much doubt that mine will make the local paper.
