There’s a small town in Sweden that has not one, not two, not three, but four elements named after it. Those elements–yttrium(Y), terbium (Tb), erbium (Er), and ytterbium (Yb)–were discovered by part-time chemist Carl Axel Arrhenius in the gadolinite, a black stone that’s also referred to as ytterbite, in Ytterby Mine on the Stockholm archipelago. From wikipedia:
In addition, three other lanthanides, holmium (Ho, named after Stockholm), thulium (Tm, named after Thule, a mythic analog of Scandinavia), and gadolinium (Gd, after the chemist Johan Gadolin) can trace their discovery to the same quarry making it the location with most elements named after it.
