Prague has been a political, cultural, educational and economic centre of central Europe for many centuries. It was the capital of the Kingdom of Bohemia, the Holy Roman Empire, Czechoslovakia and now the Czech Republic. For that reason it is home to a number of historic sites and monuments. The historical centre in Prague with all its charm, beauty, and cobblestoned streets has been included as an UNESCO World Heritage Site.
Brno is the second largest city in the Czech Republic and is the capital of the state of Moravia. It contains a number of historic sites, monuments, and attractions. As an added bonus, located a bit north of the city lies the Moravian Karst, which encompasses just over a thousand caverns and gorges. There are five caves located in the karst that are open to the public and are easily accessible by car from the city centre. Given that the train from Budapest to Prague passes through Brno, it seemed quite fitting to make a detour here for a couple of days.
