Prague Castle is officially the largest ancient castle in the world, a fact certified by the Guinness Book of Records. Covering an area of almost 70,000 square metres (750,000 square feet), the complex includes a stunning collection of palaces, churches, gardens, and alleyways that tell the story of over a thousand years of Czech history. This sprawling complex is not just a relic; it remains the official office of the President of the Czech Republic.

A Record-Breaking Castle Complex

The sheer scale of Prague Castle is its most defining feature. At approximately 570 metres (1,870 feet) long and an average of about 130 metres (430 feet) wide, it's more like a small town than a single building. This vast area contains a diverse mix of architectural styles, from Romanesque basilicas to Gothic cathedrals and Baroque palaces, reflecting its long and layered history. It has been a centre of power for kings of Bohemia, Holy Roman emperors, and Czech presidents for over a millennium.

Surprising Facts About Prague Castle

Beyond its immense size, Prague Castle holds many secrets and surprising stories within its ancient walls. Its history is filled with royal intrigue, architectural marvels, and peculiar events that make it one of the most fascinating historical sites in Europe. Here are some of the most captivating facts about this iconic landmark.

  1. It Took Nearly 600 Years to Build St. Vitus Cathedral: The magnificent Gothic cathedral, a dominant feature of the castle, began construction in 1344 under Charles IV but was only fully completed in 1929.
  2. The Bohemian Crown Jewels Are Heavily Guarded: The priceless crown jewels are stored in a hidden room within St. Vitus Cathedral. The door has seven locks, and seven different keyholders (including the President and Prime Minister) must be present to open it.
  3. It Was Home to Alchemists: The charming Golden Lane within the castle walls was, according to legend, home to alchemists working for Emperor Rudolf II in the 16th century, who tried to turn metal into gold.
  4. Franz Kafka Lived Here: The writer Franz Kafka lived for a short period between 1916 and 1917 at house No. 22 on Golden Lane, using the quiet space to write.
  5. The Castle Witnessed Defenestrations: The term 'defenestration' (the act of throwing someone out of a window) is famously associated with Prague. The Second Defenestration of Prague in 1618, when two Catholic governors were thrown from a castle window, triggered the Thirty Years' War.
  6. It's Still a Working Head of State's Office: Prague Castle isn't just a museum. It has been the seat of power for Czech rulers since the 9th century and today serves as the official residence and office of the President of the Czech Republic.
  7. A Devastating Fire Led to a Renaissance Rebirth: In 1541, a massive fire destroyed large parts of the castle. This disaster paved the way for a major reconstruction, with many buildings being rebuilt in the then-fashionable Renaissance style.
  8. The Castle Guard Uniforms Were Designed by an Oscar Winner: After the Velvet Revolution, President Václav Havel commissioned Theodor Pištěk, the costume designer for the Oscar-winning film Amadeus, to design the modern ceremonial uniforms for the Castle Guard in 1990.
  9. It Contains the Oldest Private Art Collection in Central Europe: The Lobkowicz Palace, the only privately owned building in the complex, houses an immense and valuable private art collection.
  10. There's a Daily Changing of the Guard: A ceremonial Changing of the Guard, complete with a fanfare and banner exchange, takes place in the first courtyard at 12:00 PM daily. Smaller changes happen every hour on the hour.
