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.
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.
Přemyslid dynasty left Levý Hradec at the beginning of the 10th century but it seems that settlement persevered as dense as in the 9th century. New building were constructed and fortifications regularly repaired.
The site was abandoned at the end of the 11th century as there is no further evidence of fortifications being repaired. Nevertheless, the reason why it happened so is still unknown.
The site was excavated as soon as the 19th century by archeologists Čeněk Rýzner and Josef Ladislav Píč. The main excavations took place in the 1930s and 1950s when Ivan Borkovský excavated the foundations of the original St. Clement church.
Near to Levý Hradec another early medieval fort has been first described by Josef Ladislav Píč. The excavations started there in 2000 discovered remains of much larger settlement than expected until then, comparable with Levý Hradec. The involved archeologists now assume this settlement is the Pravý Hradec (levý hradec means fort on the left side, pravý means on the right side), the fort mentioned in contemporary records but never identified.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
