Ostrava

The first written mention of Slezská Ostrava (Silesian Ostrava) dates from 1229, when it was described as a settlement. The first mention of Moravian Ostrava (Moravská Ostrava) in 1267 describes it as a township. Ostrava grew on the banks of the Ostrá River (now the Ostravice) from which it took its name. The river still divides the city into two main parts: Moravian Ostrava (Moravská Ostrava) and Silesian Ostrava (Slezská Ostrava). The settlement occupied a strategic position on the border between the two historic provinces of Moravia and Silesia and on the ancient trade route from the Baltic Sea to the Adriatic Sea known as the Amber Road. Its location helped the town to grow and flourish. However, Ostrava began to decline in importance after the Thirty Years' War, and it was occupied by Danish forces in 1626, and by Swedish forces from 1642 to 1650. …
