Prague Castle: Everything You Need to Know Before You Visit

Prague Castle is not one building. It is a city within a city — a complex of palaces, churches, gardens, towers and courtyards spread across 70,000 square metres on a hill above the Vltava. Most visitors spend an hour there and leave feeling vaguely overwhelmed. The ones who go with a private guide come away with something completely different: a story that actually makes sense.

A private Prague Castle walking tour takes you through over a thousand years of history — from the first wooden fortifications of the 9th century to the seat of Bohemian kings, Holy Roman Emperors, and the presidents of the Czech Republic today. If you're planning to visit Prague Castle and wondering how to make the most of it — this guide is for you.

The world's largest ancient castle — and why that matters

According to the Guinness Book of Records, Prague Castle is the largest ancient castle complex in the world, covering an area of almost 70,000 square metres — roughly the size of seven football pitches. Its origins date to around 870 AD, when Prince Bořivoj of the Přemyslid dynasty built the first walled structure on this hilltop. Since then, every major ruler of Bohemia has left their mark here — Romanesque stonework, Gothic cathedrals, Renaissance palaces, Baroque gardens — layer upon layer of a thousand years of power.

Today Prague Castle is still the official residence and workplace of the President of the Czech Republic. The Bohemian Crown Jewels are kept in a hidden room inside it, behind a door with seven locks held by seven different people. It is a living place, not a ruin — and that is what makes it extraordinary.

St. Vitus Cathedral — the heart of the castle

The dominant structure inside the castle complex is St. Vitus Cathedral, whose Gothic spires are visible from almost every point in Prague. Construction began in 1344 under Emperor Charles IV — and was not completed until 1929, nearly 600 years later. Inside: the tomb of St. Wenceslas, patron saint of Bohemia; the stunning stained glass windows including one designed by Alfons Mucha; and the Czech Crown Jewels chamber.

Most visitors walk through the cathedral in fifteen minutes. On our Prague Castle & Lesser Town Walking Tour your guide takes you through it at a different pace — pointing out the details that are invisible without context, and telling the stories behind the stone.

The Golden Lane — Franz Kafka lived here

One of the most charming and most overlooked parts of Prague Castle is the Golden Lane — a narrow street of tiny colourful houses originally built for castle guards and later occupied by goldsmiths and alchemists. House number 22 was rented by Franz Kafka's sister in 1916, and Kafka spent his evenings writing there. His works written during this period include A Country Doctor. The houses today hold small exhibitions of life across different centuries — and are well worth taking slowly.

The view that stops everyone

Prague Castle sits 250 metres above sea level. From the castle terraces and gardens, you look out over the red rooftops of Malá Strana, across the Vltava, all the way to the Old Town and beyond. It is one of the best views in Central Europe — and the reason most photographs of Prague are taken from this hill, or looking up at it. On our Best of Prague Car and Walking Tour we combine the castle with all the city's other highlights, seeing Prague both from above and at street level.

What most visitors miss at Prague Castle

The castle complex is enormous and the crowds concentrate at a handful of famous spots. But some of the most remarkable things are just off the main path: the Romanesque foundations visible below the Old Royal Palace, the Daliborka Tower where prisoners were once held, the quiet South Gardens with their unobstructed views, and the changing of the guard at the castle gates — every hour on the hour. A private guide knows where to go and when — and which parts of the castle are worth your time versus which are not.

Prague Castle as the centrepiece of your Prague visit

Prague Castle anchors the left bank of the Vltava, with the charming streets of Malá Strana running down from its gates toward Charles Bridge. The walk from the castle down through Lesser Town to the bridge is one of the most beautiful walks in Europe — cobblestones, Baroque palaces, hidden gardens, the narrowest street in Prague, and the sound of the city below. It connects naturally into a full day that covers both banks of the river and everything between them.

Our Prague Castle & Lesser Town Walking Tour follows exactly this route — from the castle complex down through the hidden streets of Malá Strana to Charles Bridge. Private, just your group, everything explained.

Frequently asked questions about the Prague Castle walking tour

Is Prague Castle free to visit? The castle courtyards and grounds are free and open daily from 6am to 10pm. The interiors — St. Vitus Cathedral, Old Royal Palace, St. George's Basilica and Golden Lane — require a ticket, which your guide arranges on the day.

What is the best time to visit Prague Castle to avoid crowds? Early morning is best — the castle opens at 6am and the first hour or so is significantly quieter than the rest of the day. Weekdays are less crowded than weekends. Summer afternoons are the busiest time.

Is a private Prague Castle tour better than going alone? The castle complex is vast and the history spans over a thousand years across dozens of buildings. Without a guide, most visitors see the outside of things without understanding what they're looking at. A private guide transforms the visit from sightseeing into an experience you'll actually remember.

What does the Prague Castle & Lesser Town Walking Tour include? The tour covers the castle complex, St. Vitus Cathedral, Golden Lane, the Old Royal Palace, and the walk down through Malá Strana to Charles Bridge — with sweeping views over the city throughout.
