Prague Castle
Largest ancient castle complex and seat of Czech presidents.
Prague Castle (Czech: Pražský hrad) is a large castle complex in Prague, Czech Republic, that serves as the official home and office of the Czech president. Construction began in the 9th century, and over the centuries it has been the seat of power for Bohemian kings, Holy Roman emperors, and Czechoslovak presidents. Because of this, the name "Prague Castle" or simply "Hrad" is often used to refer to the president and their staff. The Bohemian Crown Jewels are stored in a secret room inside the castle. Recognized by the Guinness Book of Records as the largest ancient castle in the world, it covers nearly 70,000 square meters, stretches about 570 meters in length, and averages about 130 meters in width.
The castle’s history starts in 870 with the construction of its first stone building, the Church of the Virgin Mary. In the first half of the 10th century, under Duke Vratislaus I and his son Wenceslaus I, the Basilica of Saint George and the Basilica of St. Vitus were founded. The first convent in Bohemia was established next to St. George’s Church, and a Romanesque palace was built in the 12th century. Venetian coins from the 13th century found there were studied by numismatist Zdenka Nemeškalová-Jiroudková.
During the medieval period, King Ottokar II of Bohemia strengthened the fortifications and rebuilt the royal palace for housing and ceremonial use. In the 14th century, Charles IV rebuilt the palace in Gothic style and reinforced the defenses. Work began on a vast Gothic church to replace the rotunda and basilica of St. Vitus, though it was not finished for nearly six centuries. The castle was left uninhabited during the Hussite Wars and the following decades. In 1485, King Vladislaus II Jagiellon started rebuilding, adding the large Vladislav Hall by architect Benedikt Rejt and new defense towers on the north side. A major fire in 1541 destroyed large parts of the castle. Under the Habsburgs, Renaissance-style buildings were added, including the Belvedere summer palace built by Ferdinand I for his wife Anne. Rudolph II made Prague Castle his main residence, founding the northern wing with the Spanish Hall to display his art collection. The Third Defenestration of Prague in 1618 occurred at the castle, triggering the Bohemian Revolt. During the wars that followed, the castle fell into disrepair, and many works from Rudolph II’s collection were looted by Swedes in 1648 during the final battle of the Thirty Years' War. The last major rebuilding was carried out by Empress Maria Theresa in the late 18th century. After Ferdinand I abdicated in 1848, his nephew Franz Joseph took the throne, and Ferdinand I made the castle his home.
In 1918, the castle became the seat of the president of the new Czechoslovak Republic, Tomáš Masaryk. Slovenian architect Jože Plečnik renovated the New Royal Palace and gardens, and St. Vitus Cathedral was finally completed on 28 September 1929. Further renovations continued in 1936 under Plečnik’s successor, Pavel Janák.
On 15 March 1939, after Nazi Germany forced President Emil Hácha to surrender his nation, Adolf Hitler spent a night at Prague Castle, reportedly surveying his new possession. During the Nazi occupation, the castle served as headquarters for Reinhard Heydrich, the Reich Protector of Bohemia and Moravia. A popular legend says that a usurper who places the Bohemian crown on his head will die within a year; Heydrich is rumored to have done so. Less than a year later, on 27 May 1942, he was ambushed by British-trained resistance soldiers on his way to the castle and died from infected wounds a week later. His firstborn son, Klaus, died the following year in a traffic accident, also matching the legend.
After the liberation of Czechoslovakia and the 1948 communist coup, the castle housed the offices of the communist government. Following the country’s split in 1993 into the Czech Republic and Slovakia, the castle became the seat of the new Czech head of state. President Václav Havel, following Masaryk’s example, commissioned architect Bořek Šípek to oversee post-communist improvements, including a facelift of the castle’s painting gallery.
The castle’s architecture blends styles from many periods, reflecting its long history. It includes the Gothic St. Vitus Cathedral, the Romanesque Basilica of St. George, a monastery, several palaces, gardens, and defense towers. Most areas are open to tourists. The castle houses museums such as the National Gallery’s collection of Bohemian baroque and mannerist art, an exhibition on Czech history, a Toy Museum, and the picture gallery based on Rudolph II’s collection. The Summer Shakespeare Festival is held regularly in the Burgrave Palace courtyard. The surrounding neighborhood is called Hradčany.

Lore & Background
The castle's history began in 870 when its first walled building, the Church of the Virgin Mary, was built. The Basilica of Saint George and the Basilica of St. Vitus were founded under the reign of Vratislaus I, Duke of Bohemia and his son Wenceslaus I in the first half of the 10th century. A Romanesque palace was erected here during the 12th century. King Ottokar II of Bohemia improved fortifications and rebuilt the royal palace for representation and housing. In the 14th century, under Charles IV, the royal palace was rebuilt in Gothic style and fortifications strengthened. Building began on a vast Gothic church that was completed almost six centuries later. During the Hussite Wars and following decades, the castle was not inhabited. In 1485, King Vladislaus II Jagiellon began to rebuild, adding the massive Vladislav Hall by Benedikt Rejt. A large fire in 1541 destroyed large parts.

Scale and Unbroken Sovereignty
Prague Castle holds a Guinness Book of Records designation as the world's largest ancient castle, stretching roughly 570 metres in length with an average width of about 130 metres and covering nearly 70,000 square metres. What makes this footprint remarkable is not merely its size but the unbroken thread of political authority it has housed since the 9th century. The first walled structure, the Church of the Virgin Mary, dates to 870, and from that modest beginning the complex grew into the seat of Bohemian kings, Holy Roman emperors, and later the presidents of Czechoslovakia and the Czech Republic. The term "Hrad" has become a metonymy so deep-rooted that referring to the castle is often shorthand for the sitting president, his staff, and his advisors. Even the Bohemian Crown Jewels, symbols of medieval sovereignty, remain locked in a hidden room within these walls, linking the present-day head of state to a lineage of power that spans more than a millennium.
A Palimpsest of Architectural Eras
Walking through Prague Castle is like reading a building history of Europe compressed into one site. The Romanesque Basilica of St. George, founded in the first half of the 10th century under Duke Vratislaus I and his son Wenceslaus I, still stands as the oldest surviving church structure within the complex. Beside it, the Gothic St. Vitus Cathedral began construction in the 14th century under Charles IV, replacing an earlier rotunda and basilica, yet was not completed until 28 September 1929—nearly six centuries of continuous work. The Old Royal Palace carries layers from the 12th-century Romanesque era through Charles IV's Gothic rebuild, the massive Vladislav Hall added in the late 15th century by master builder Benedikt Rejt, and Renaissance additions under the Habsburgs, including Queen Anne's Summer Palace commissioned by Ferdinand I. The northern wing, with its Spanish Hall, was created by Rudolph II to display his art collections. Even the defence towers on the north side and the diverse churches—the All Saints Church, the Holy Cross Chapel—testify to a site that has been rebuilt, expanded, and reimagined across every major architectural movement of the last thousand years.
Crises, Usurpers, and the Crown's Curse
Few places in Europe have witnessed so many violent ruptures of political order within a single complex. In 1618, the Third Defenestration of Prague—when officials were thrown from the castle windows—ignited the Bohemian Revolt and set the stage for the Thirty Years' War. Decades later, Swedish forces looted many of Rudolph II's treasured artworks during the 1648 Battle of Prague. The castle's darkest chapter arrived in 1939, when Emil Hácha, suffering a heart attack during negotiations, was coerced into surrendering Czech sovereignty, and Adolf Hitler spent a night within the walls surveying his new possession. The following years saw Reinhard Heydrich, the Reich Protector, establish his headquarters here. A persistent legend holds that anyone who places the Bohemian crown on their head is doomed to die within a year. Heydrich, according to rumor, did exactly that; he was ambushed in May 1942 by British-trained resistance fighters and died a week later of infected wounds. His firstborn son Klaus perished in a traffic accident the following year, seemingly fulfilling the curse.
Living Culture and the Modern Presidency
Today Prague Castle is simultaneously a working government office, a museum complex, and the Czech Republic's most-visited tourist destination, drawing 2.59 million visitors in 2024 alone. The site houses the National Gallery's collection of Bohemian baroque and mannerist art, a dedicated exhibition on Czech history, a Toy Museum, and the picture gallery rooted in Rudolph II's original collection. The courtyard of Burgrave Palace hosts the Summer Shakespeare Festival, bringing contemporary performance to a space that once echoed with royal court life. The surrounding neighbourhood, Hradčany, frames the complex in a residential context that softens its imperial grandeur. Architecturally, the castle's post-communist renewal mirrors an earlier pattern: just as Tomáš Masaryk commissioned Slovenian architect Jože Plečnik to renovate the New Royal Palace and gardens in the 1920s, President Václav Havel later entrusted Bořek Šípek with the facelift of the painting gallery. This continuity of presidential stewardship—each leader commissioning a new generation of architects to shape the castle's public face—reinforces the idea that Hrad is not a frozen monument but a living institution, perpetually being remade for the present while carrying the weight of its past.
Common Misconceptions (Editorial)
1. Some believe St. Vitus Cathedral was built in the medieval period, but it was not completed until 28 September 1929—nearly six centuries after construction began in the 14th century. 2. A common misconception is that the castle was always continuously inhabited by rulers; in fact, during the Hussite Wars and following decades, the castle was not inhabited.
Why It Matters (Editorial)
Prague Castle endures not only as the largest ancient castle in the world but as a living symbol of Czech sovereignty across more than a millennium of political upheaval. From housing kings and Holy Roman emperors to serving as the seat of democratic presidents and surviving Nazi occupation, its walls embody the resilience and continuity of the Czech state.
