Ostrava grew in importance due to its position at the heart of a major coalfield, becoming an important industrial centre. It was previously known as the country's "steel heart" thanks to its status as a coal-mining and metallurgical centre. Since the 1990s Ostrava has been transformed into a modern cultural city, with numerous theatres, galleries and other cultural facilities.
