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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
