Here is the flag of Slavětín nad Metují in Hradec Králové region (Náchod
okres) in the Czechian Republic. It was approved 5 October 2004, and
published in Petr Exner's Vexillological Lexicon of Czech municipal
flags 2004.
At the municipal site
is the Coat of Arms - so one can see that the flag is a BoA: blue, in center a vertical
stripe, consisting of three equally high parts of black, white and red;
surrounding the central stripe is a yellow fish.
