Prague is the capital and largest city of the Czech Republic. Situated on the Vltava river in central Bohemia, it is home to approximately 1.2 million people. Since 1992, the historic center of Prague has been included in the UNESCO list of World Heritage Sites. According to Guinness World Records, Prague Castle is the largest ancient castle in the world.
The land where Prague was to be built has been settled since the Paleolithic Age. Several thousands of years ago, there were trade routes connecting southern parts of Europe to northern Europe which passed through this area, following the course of the river. From around 500 BC the Celtic tribe known as the Boii, were the first known inhabitants of this region known by name. The Boii named the region Bohemia and the river Vltava. In between the 6th and 9th centuries AD the Germanic tribe Marcomanni migrated to Bohemia and other Germanic tribes followed during the 5th century AD, but in the 6th century their elites and majority of inhabitants moved to the Danubian area which enabled a Slavic tribe invading from the West, to settle this area. The Czech Slavic tribe came to Bohemia in the 6th century and Forefather Czech became the founder of the Czech nation.
