Positioned in Central Europe and the western Balkans, Croatia stretches across multiple ecosystems. Continental grasslands with floodplains and hills form the interior, bordered by the Karstic Dinaric Mountain chain on the eastern side, which stretches down to the sparkling blue island-saturated coastline of the Adriatic Sea. Contested for centuries by different powers, Roman, Austro-Hungarian, Ottoman, Italian, and Dubrovnik influences are all still visible in the culture, history, architecture, language, and cuisine. Croatia is a member state of the European Union and part of the Schengen Area and the Eurozone.
