Dostinika

Destinikon (Greek: Δεστινίκον), rendered in Serbian as Dostinik (Serbian Cyrillic: Достиник) or Dostinika (Достиника), was one of eight inhabited cities (καστρα/kastra) of "baptized Serbia" (the hinterland of the Serbian Principality), mentioned in De Administrando Imperio (950s, abbr. DAI). The exact location is undetermined, although modern studies point to locations in Raška and Metohija.

The DAI mentions Destinikon as the first among the enumerated cities ("Destinikon, Tzernabouskeï, Megyretous, Dresneïk, Lesnik, Salines, Katera, Desnik") of "baptized Serbia". In chapter 32, the DAI tells of Klonimir, an exiled dynastical member in Bulgaria, who marched an army into Serbia, entering the city of Destinikon with the intent of seizing the throne, but was defeated by Prince Petar, in ca. 896.
