Prague Castle

Prague Castle rises above the Vltava River on Hradčany hill, a sprawling complex that has watched over Prague since the city's earliest days. Once the seat of Bohemian kings, it now serves as the official residence of the President of the Czech Republic.

Where does the name come from and how old is the castle?

The castle takes its name from Hradčany, the district it crowns, and is sometimes referred to simply as the Castle on Hradčany. Its story begins in the 9th century, when Prince Bořivoj of the Přemyslid dynasty built the first fortifications on this hilltop, turning it into a center of power long before Prague grew into the city we know today. Construction never really stopped after that — each century added its own layer, so the present-day complex blends Romanesque remnants, Gothic reconstructions, and later Renaissance and Baroque additions into a single, continuously evolving site.

Why is it called the largest castle in the world?

Guinness World Records lists Prague Castle as the largest coherent castle complex on Earth, covering nearly 70,000 square meters. It isn't a single building but a vast arrangement of palaces, churches, courtyards, and gardens that grew side by side over the centuries. The entire complex is inscribed on the UNESCO World Heritage list, a recognition of both its historical depth and architectural range.

What can visitors find inside the castle grounds?

At the heart of the complex stands St. Vitus Cathedral. Its origins trace back to 925, when Prince Wenceslas founded a Romanesque rotunda on the site; after 1060 it was rebuilt into a three-nave basilica with two towers. The Gothic cathedral visitors see today was begun in 1344 under Charles IV, but wars and plagues repeatedly halted the work, and the building wasn't actually completed until 1929. Beyond the cathedral, the grounds also hold the Old Royal Palace, the Basilica of St. George, and Golden Lane, a row of small houses once occupied by castle craftsmen.

What role has the castle played through the centuries?

For generations it was the residence of Bohemian rulers, and its cathedral hosted the coronations of Czech kings and queens. St. Vitus Cathedral also became the burial place of patron saints, sovereigns, and high-ranking clergy, cementing the castle's status as the spiritual and political center of the kingdom. That role as a seat of power never really disappeared: since the founding of independent Czechoslovakia and later the Czech Republic, the castle has remained the official residence of the head of state, combining its life as an open historic monument with an active administrative function.
