There are 4 elements named after a small swedish town in the periodic system of elements. The town is Ytterby. The elements are the rare earth elements (which actuallyt isn't that rare) Yttrium (Y), Erbium (Er), Terbium (Tb) and Ytterbium (Yb). In addition, one of the guys involved in the detection of those is the finnish 19th century chemist (and physicist, and mineralogist - who knows if he didn't play the piano as well) Johan Gadolin, after which Gadolinium is named. Gadolinium is used in MRI contrast media.
In minerals from the mine outside of Ytterby (which is located in Vaxholm's municipality, in the archipelago outside of Stockholm)) a grand total of 8 new elements have been discovered. Not only Yttrium, Ytterbium, Terbium & Erbium, but also Holmium, Skandium, Tulium & Gadolinium. These are named after the latin name for Stockholm (Holmia (Holmium)), Scandinavia (Skandium), the latin name for Scandinavia (Thule (Thulium)) and Johan Gadolin (Gadolinium).
