Charles Bridge Through the Course of History

Predecessors of the Bridge: From Footbridges to the Judith Bridge

The Ancient Need to Connect the Banks

The need to connect both banks of the Vltava River in Prague is ancient. As early as the 10th century, a wooden bridge stood here.

Judith Bridge – The First Stone Bridge

The first true stone bridge in Prague was the Judith Bridge, named after Judith of Thuringia, the wife of King Vladislav II. It was built between 1160 and 1172 and was a significant construction feat for its time. It served the people of Prague for nearly two centuries before it was destroyed in February 1342 by a catastrophic flood caused by melting ice.

Legacy of the Judith Bridge

Remnants of this Romanesque bridge, including the foundations of some pillars and the Lesser Town Judith Tower, are still visible today and testify to the continuity of settlement and transport routes in this locality.

Thus, the Charles Bridge was not built "on a greenfield," but followed a centuries-old tradition and experience, with its builders striving to overcome the shortcomings of their predecessors and create a more durable and resilient structure.

Floods – The Eternal Enemy

Early Damage During Construction

The Vltava, though a life-giving river, has always been a great threat to Prague's bridges. The Charles Bridge was threatened by floods practically from the very beginning of its existence. Even during its construction, the unfinished work was damaged several times, for example, in 1359, 1367, and 1370.

Catastrophic Flood of 1432

Over the centuries, a series of other devastating floods followed. The year 1432 brought one of the worst floods in Prague's history, severely damaging five pillars of the Charles Bridge and breaching it in three places. Repairs lasted an incredible 71 years, until 1503.

Flood of 1784 and Its Victims

Another major flood in 1784 heavily damaged five bridge pillars. It even swept away a military guardhouse located on one of the pillars, and four soldiers lost their lives.

Repairs at that time were carried out using traditional medieval techniques – coffer dams were built around the damaged pillars, the foundations were reinforced with new oak piles, and so-called millstones were laid on them.

The Most Destructive Flood of 1890

The flood of 1890 is considered one of the most catastrophic. A huge number of loose rafts and floating timber crashed into the bridge, creating a dam. The water pressure subsequently broke through three bridge arches and overturned two undermined pillars.

Some statues also fell into the raging Vltava at that time, including valuable works by Ferdinand Maxmilian Brokoff – St. Ignatius of Loyola and St. Francis Xavier. During the subsequent repair, more modern technology for founding pillars using steel caissons was used for the first time.

Despite these repeated disasters, the Charles Bridge was always repaired, which testifies to its immense importance for the city. Each major repair was not only a test of resilience but also an opportunity to use new technologies and knowledge. The bridge thus became a symbol not only of building skill but also of Prague's indomitability and ability to regenerate.

The Bridge in the Whirlwind of Wars

Hussite Wars and the Thirty Years' War

Thanks to its strategic location as a key connection between the Old Town and the Lesser Town (and Prague Castle), the Charles Bridge inevitably became the scene of military confrontations. The bridge was damaged as early as the Hussite Wars in the 15th century.

It played a significant role at the end of the Thirty Years' War, in 1648, when fierce battles between Prague's defenders and Swedish troops took place on it. It was then that the Old Town Bridge Tower was seriously damaged, especially its sculptural decoration on the side facing the river.

The Revolutionary Year 1848

In the revolutionary year of 1848, barricades were also erected on the bridge, and it witnessed fighting. These wartime events not only caused physical damage to the structure itself but also layered further historical and symbolic meanings onto the bridge, recalling its role in the city's defense and in key moments of Czech history.

Prague's Traffic Artery: From Horse-Drawn Trams to a Pedestrian Zone

The Only Connection Across the Vltava

For centuries, until 1841, the Charles Bridge was the only "land" communication across the Vltava in Prague. It served all traffic – pedestrians, carriages, riders.

Era of Trams and Automobiles

In the 19th and 20th centuries, its transport use continued to change. Between 1883 and 1905, a horse-drawn tram line ran across the bridge. Later, it was replaced by electric trams, and cars also drove across the bridge until 1965.

Transformation into a Pedestrian Zone

However, the increasing intensity of traffic and vibrations were not beneficial to the bridge. After a general overhaul between 1965 and 1978, the Charles Bridge was completely closed to traffic and reserved only for pedestrians.

This change reflects not only the technological development of transport but, above all, a shift in the perception of historical monuments – from primarily functional structures to protected cultural symbols, where the emphasis is on their preservation and the experience for visitors.

Modern Repairs and Their Challenges

General Overhaul in 1965–1978

Even in modern times, the Charles Bridge requires constant care and repairs to be preserved for future generations. A significant general overhaul took place between 1965 and 1978.

During this time, all damaged sandstone blocks in the bridge's facing were replaced, the original asphalt surface was replaced with split granite strips, and a reinforced concrete slab was inserted into the structure to statically secure the bridge.

Repair in 2007–2010 and Its Controversies

Another more extensive repair took place between 2007 and 2010, when the railing, bridge deck, and insulation were reconstructed. However, this repair was accompanied by criticism from some conservationists and part of the public, for example, due to the extent of the replacement of original stone blocks or due to formal errors in the preparation and implementation of the project.

The Prague City Hall even fined itself for some errors, but higher sanctions were later imposed by the Ministry of Culture, although the offense eventually became statute-barred.

Plans for the Future

Further stages of repairs are planned for the future, which should include the reconstruction of the bridge's facing, the statue pedestals, and especially the substructure, i.e., all the bridge arches.

Modern repairs highlight the constant need for maintenance of such an exposed monument, but also the complex ethical and technical issues associated with restoration.

The controversies that accompanied some repairs reflect growing public interest and a legitimate debate about how best to care for our most valuable cultural heritage, how to combine modern technologies with the requirements for preserving authenticity.
