Croatia's rivers belong to the Adriatic and the Black Sea basin. The rivers in the interior are large and calmer (Sava, Drava, Danube).
The subdivisions of Croatia on the first level are the 20 counties (županija, pl. županije) and one city-county (grad, "city"). On the second level these are municipalities (općina, pl. općine) and towns (also named grad, pl. gradovi).Both of these type of subdivisions consist of settlements(naselje, pl. naselja). The 1st- and 2nd-level subdivisions are self-governed, while naselja are used mainly for statistical purposes, though they can also institute one or more levels of self-government, typically in cities.
Wine in Croatia has a long, long history. It was the Greek settlers who first introduced vineyards to the Croatian coast in the 5th century BC and wine production has flourished ever since. During the Homeland War, many wineries and vineyards were destroyed but the winemaking industry has rushed back.
