text: Zemplén is named after its castle as well. The name is derived from the Slovak word zem or the Slavic zemlja, meaning 'earth, soil, ground' or 'country.' The castle, like its name indicates, was a motte with earthen walls; its remnants can still be seen near the Slovak village Zemplín.
  Note that besides these three castles, there were other castles in the old counties which became the modern Borsod-Abaúj-Zemplén, such as the well-known Füzérvár.
  Coat of arms and flag
  The county's coat of arms was created in 1991 from the coats of arms of the former counties now forming parts of Borsod-Abaúj-Zemplén. From left to right: Coat of arms of Abaúj-Torna county. – Coat of arms of Zemplén county. – Coat of arms of Borsod county. – Coat of arms of Gömör / Gömör-Kishont county (with its red background color changed to the same blue as used in the coat of arms of Abaúj).
  The flag is vertically divided into two equal sections (red and blue), with the coat of arms on it, and the county's name embroidered with gold thread under the coat of arms. Its ratio is 2:1. The use of both coat of arms and flag is regulated by the county council.
