I also learned on Wikipedia about a town named Ytterby in the Stockholm archipelago on an island called Resarö. For some reason, this tiny town has a lot of really unusual mineral deposits, and is responsible for the discovery and/or naming of a whole slew of chemical elements: yttrium, ytterbium, terbium, erbium, gadolinium, thulmium (Latin term for the Nordic countries), and holmium (Latin for Stockholm).
