Gordoservon or Gordoserbon or Gordoserba (Greek: Γορδόσερβον; Serbian: Гордосервон, Гордосербон) was an early medieval Byzantine city, and a bishopric, suffragan of the Metropolis of Nicaea, in the region of Bithynia, Asia Minor. It is mentioned in several ecclesiastical sources from the period between the 7th and the 9th century. Most notably, the city is mentioned in the acts of the Council of Trullo (691-692), as a seat of bishop Isidore, who attended the council.[1]
The exact location of this city, and etymology of its name, have been a subject of interest for scholars, who proposed several solutions for both questions.[2]
