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.
