Castles were built to keep enemies out. Palaces were built to leave visitors speechless. Europe’s greatest royal residences are something else entirely — vast, gilded, and still capable of stopping you cold the moment you step through the gates.
Versailles: where excess became an art form
The Palace of Versailles was built to express a single idea: that Louis XIV was the most powerful ruler on earth. With 700 rooms, a Hall of Mirrors stretching 73 metres long, and gardens covering 800 hectares, it remains one of the most overwhelming buildings ever constructed.
What makes Versailles extraordinary isn’t just the scale. It’s the deliberate theatricality of every room — the way the light falls across the painted ceilings, the golden furniture arranged to suggest a court that never entirely left. Louis XIV moved the French court here permanently in 1682, and for over a century, Versailles was the centre of the world.
Schönbrunn: the Habsburgs’ golden palace
Vienna’s Schönbrunn Palace was the summer residence of the Habsburg imperial family for over 300 years. It has 1,441 rooms, though only 40 are open to visitors. The ones you can see — the Great Gallery, the Millions Room lined with 260 rosewood panels inlaid with Indo-Persian miniatures, and the imperial apartments — are astonishing enough.
Mozart performed here as a six-year-old prodigy. Napoleon used it as his headquarters twice. Franz Joseph I was born here and died here — 86 years later — in 1916. Few buildings in Europe have absorbed quite so much history into their walls.
Hampton Court: Henry VIII’s favourite home
Henry VIII acquired Hampton Court Palace in 1529 from Cardinal Wolsey, who had built it rather too grandly for a man not quite equal to a king. Henry extended it, feasted in its Great Hall, and spent more nights here than in any other royal residence. Two of his six wives were associated with the palace — Anne Boleyn celebrated here before her fall; Jane Seymour died here after giving birth to the future Edward VI.
Today you can walk through the state apartments, explore the Tudor kitchens that once fed 1,000 people a day, and get genuinely lost in the famous maze. If you’re curious about what life in these great royal households was actually like, Hampton Court brings it alive better than almost anywhere in England.
Topkapi: where the Ottoman sultans held court
For four centuries, Topkapi Palace in Istanbul was the administrative heart of the Ottoman Empire. It’s less a single building and more a sprawling complex of courtyards, throne rooms, treasure houses, and the Harem — the private household where the sultan’s family lived behind locked doors and an elaborate hierarchy of eunuchs and servants.
The palace also houses sacred Islamic relics, including the sword and cloak of the Prophet Muhammad and the staff of Moses. The Treasury contains the Topkapi Dagger and the 86-carat Spoonmaker’s Diamond. The views across the Bosphorus from the palace gardens are extraordinary — a reminder that this was not just a seat of power, but a place chosen for its position at the very crossroads of the world.

Sintra: Portugal’s hillside palace town
An hour from Lisbon, Sintra contains more remarkable palaces per square mile than almost anywhere in Europe. The National Palace, with its two distinctive conical chimneys rising above the town, dates to the 14th century and was a favourite retreat of Portuguese royalty for 600 years.
A short climb above sits the Pena Palace — built in the 1840s in a riot of Romantic architecture that pulls from Moorish, Gothic, Renaissance, and Manueline styles. It was described by Hans Christian Andersen as “the most beautiful thing I have ever seen.” Walk to it through the wooded hillside on a misty morning and it’s not difficult to understand why.
Peterhof: Russia’s answer to Versailles
Peter the Great built Peterhof, on the Gulf of Finland near St Petersburg, specifically to rival Versailles. He succeeded: the Grand Palace’s gilded facade and the Grand Cascade below it — 64 fountains and 225 statues channelling water from a natural spring without any pumping mechanism — make it one of the most visually spectacular sites in Europe.
Peter was obsessed with the sea. The palace’s lower gardens run down to the Gulf of Finland, and the fountains were designed to announce his empire’s naval power to the world. Go in summer when the fountains run and the gilded statues catch the light. It is, by any measure, absurd — and utterly magnificent.
Palaces and castles often share the same stories. If you want to explore the hidden and lesser-known side of royal history, there are extraordinary places still waiting to be discovered.
Frequently asked questions
Which is the largest royal palace in Europe?
The Royal Palace of Madrid (Palacio Real) is the largest royal palace in Europe still in official use, with over 3,400 rooms and 135,000 square metres of floor space. It’s used for state ceremonies, though Spain’s royal family lives in the smaller Zarzuela Palace on the outskirts of the city. Versailles, while larger in total area including its gardens, is no longer a working royal residence.
Can you stay overnight in a royal palace?
A small number of former royal residences now offer accommodation. Castle and palace hotels across Europe range from Scottish baronial estates to converted French chateaux. None of the great state palaces — Versailles, Schönbrunn, Topkapi — offer overnight stays, but the Parador network in Spain includes several historic royal residences.
What is the difference between a castle and a palace?
A castle was designed primarily for defence — thick walls, towers, moats, and battlements. A palace is designed primarily for grandeur: a royal or aristocratic residence built to impress rather than to withstand a siege. In practice, the distinction blurs considerably. Many European palaces began as castles, and many buildings carry both names at different points in their history. The key question is usually: was it built to keep people out, or to fill them with awe?

Stand in the Hall of Mirrors at Versailles, or beneath the gilded ceilings of Schönbrunn, and you understand something that no history book quite conveys: these buildings were made by people who genuinely believed their power had no limits. Walking through them today, centuries on, it’s hard to entirely disagree.
