The city was once the capital, in the 18th century. I think I read that it is the 2nd largest city, after Zagreb. Scenic town center area, the highlight is the Stari Grad "old town", a 12th century castle with some huge embankments to create a moat that were added later like in the 16th century. The castle is in pretty good shape, having had several restorations over the years most recently in the 1980s.
The town cemetery is also unique with enormous hedges 12 feet tall around every plot, to create a very attractive gardens effect. The cemetery manager didn't want individual monuments to compete with each other, so the hedges dominate everything else in the cemetery.
