In 1989, after the Velvet Revolution ended the communist regime that ruled former Czechoslovakia, millions of travelers from the west started coming in droves to what is now the Czech Republic (after CZ and SL split in the amicable 1993 Velvet Divorce), especially the Czech capital Prague. And with good reason. This Central European country really has a lot to boast about, and Prague is definitely one of the most beautiful cities in the whole world. The country's ancient tradition of brewing beer (Budweiser was originally a Czech beer, the original - Budvar - is still brewed in České Budějovice, where you'll find the largest town square in Europe) makes your stay in the country an even more enjoyable one.
But don't limit your stay to Prague! There are several beautifully preserved medieval cities, most notably Ceský Krumlov and Kutna Hora in Bohemia and Znojmo in south Moravia, near the Austrian border. Karlovy Vary (Carlsbad) is a famous spa town, where you can take curative mineral water treatments while mingling with the rich and famous, many from Russia.
