Levý Hradec is an early medieval Bohemian gord situated 3 km northwest of Prague borders near Roztoky, in the Czech Republic.
The first historical evidence concerning Levý Hradec comes from Kristián who wrote about the St. Clement church and its first priest Kaich.
Kristián also mentions Saint Adalbert of Slavník's dynasty to be elected here into his bishopric office on 19 February 982.
The site was excavated as soon as the 19th century by archeologists Čeněk Rýzner and Josef Ladislav Píč.
The excavations started there in 2000 discovered remains of much larger settlement than expected until then, comparable with Levý Hradec.
