The county seat is the town of Koszalin and the powiat includes
the area around it, but not the city itself which forms its own separate
urban powiat.
Coat of arms and flag of Koszalin County adopted during the first term
of the County Parliament (1999-2002). Unfortunately, I have no knowledge
of the law about the adoption of new symbols.
In the Polish edition of Wikipedia, I found the images of the symbols
of Koszalin County. Please see this
page.
I can confirm the real use, because I have seen some pictures of the
meeting of County Council. Behind the meeting presidium was this county
flag.
