This is one of the reasons I like coming to Budapest: the chance to spend time in buildings like this.

I think of all the academies of science I've visited, this is the one that has the best location by far: on the banks of the Danube, right beside the Chain Bridge, with the castle, Parliament, and St. Stephen's all nearby. Really something.
And it's a beautifully-maintained building. The Hungarians take their science seriously.
