Charles Bridge (Czech: Karlův most [ˈkarluːf ˈmost] (About this soundlisten)) is a historic bridge that crosses the Vltava river in Prague, Czech Republic. Its construction started in 1357 under the auspices of King Charles IV, and finished in the beginning of the 15th century. The bridge replaced the old Judith Bridge built 1158–1172 that had been badly damaged by a flood in 1342. This new bridge was originally called Stone Bridge (Kamenný most) or Prague Bridge (Pražský most) but has been "Charles Bridge" since 1870. As the only means of crossing the river Vltava (Moldau) until 1841, Charles Bridge was the most important connection between Prague Castle and the city's Old Town and adjacent areas. This "solid-land" connection made Prague important as a trade route between Eastern and Western Europe. The bridge is 516 metres (1,693 ft) long and nearly 10 metres (33 ft) wide, following the example of the Stone Bridge in Regensburg, it was built as a bow bridge with 16 arches shielded by ice guards. It is protected by three bridge towers, two on the Lesser Quarter side (including the Malá Strana Bridge Tower) and one on the Old Town side, the Old Town Bridge Tower. The bridge is decorated by a continuous alley of 30 statues and statuaries, most of them baroque-style, originally erected around 1700 but now all replaced by replicas. Repairs are scheduled to start in late 2019, and should take around 20 years. The avenue of 30 mostly baroque statues and statuaries situated on the balustrade forms a unique connection of artistic styles with the underlying gothic bridge. Most sculptures were erected between 1683 and 1714. They depict various saints and patron saints venerated at that time. The most prominent Bohemian sculptors of the time took part in decorating the bridge, such as Matthias Braun, Jan Brokoff, and his sons Michael Joseph and Ferdinand Maxmilian. Among the most notable sculptures, one can find the statuaries of St. Luthgard, the Holy Crucifix and Calvary, and John of Nepomuk. Well known also is the statue of the knight Bruncvík, although it was erected some 200 years later and does not belong to the main avenue. Beginning in 1965, all of the statues have been systematically replaced by replicas, and the originals have been exhibited in the Lapidarium of the National Museum.
