The Vltava (/ˈvʊltəvə, ˈvʌl-/ VU(U)L-tə-və, Czech: [ˈvl̩tava] ; German: Moldau [ˈmɔldaʊ] ) is the longest river in the Czech Republic, a left tributary of the Elbe River. It runs southeast along the Bohemian Forest and then north across Bohemia, through Český Krumlov, České Budějovice, and Prague. It is commonly referred to as the "Czech national river".
Levý Hradec is an early medieval Bohemian gord situated 3 km northwest of Prague borders near Roztoky, in the Czech Republic. This fortified settlement served as the original seat of Bořivoj I, the first known Přemyslid ruler. It was built on a promontory on the left bank of the Vltava River approximately in mid-9th century.
The first Christian church was built here shortly after Bořivoj I converted to Christianity. This church was consecrated to St. Clement.
