Moravia is one of the three historical Czech Lands, the other two being Bohemia and Czech Silesia. These regions no longer exist as administrative entities, but they are mentioned in the Czech constitution and their symbols appear in the Czech coat of arms. Moravia is the second largest and second most populous of these regions (after Bohemia). It boasts seven UNESCO World Heritage Sites. The biggest city and the former capital of Moravia is the beautiful city of Brno.
