Sanssouci

Listen to the gravel first. It crunches softly under every step on the long path below the terraces. Somewhere a fountain splashes, and the wind moves through rows of grapevines. Above you, a low yellow palace sits at the very top of the hill. It is only one storey tall, with a small green dome. It looks less like a royal residence and more like a garden pavilion. That was exactly the intention.

This is Sanssouci, in Potsdam, just outside Berlin. The name is French, and it means "without worries". The palace was built in the 1740s for Frederick the Second of Prussia, the king history calls Frederick the Great. He was a soldier, but he wanted a place to escape war, politics and court ceremony. Here he wanted books, music, conversation and his dogs. Nothing else.

Frederick sketched the first ideas himself. His friend, the architect Georg Wenzeslaus von Knobelsdorff, turned those sketches into a building. The two men did not always agree. Knobelsdorff wanted a raised basement, so that the palace would look grander from below. Frederick refused. He wanted to step straight out of his rooms onto the terrace and into the garden. The king won the argument, and you can see the result today.

Now look down the hill. The six wide terraces were planted as a vineyard before the palace was even finished. Their curved walls hold small glazed niches. Inside, vines and fig trees grow against the warm stone and stay protected from the cold. Prussia is not a natural wine country. These terraces were a royal experiment in growing southern fruit under a northern sky. Many niches are still planted today.

Here is a detail most visitors walk straight past. Look up at the inscription across the front of the palace. It reads "Sans, Souci" — with a punctuation mark in the middle. Nobody knows for certain why it is there. Some people say it was a craftsman's mistake. Others think Frederick enjoyed a private joke in Latin or French. The mark has puzzled historians for a long time... and it still does.

On the garden side, the facade carries carved stone figures between the tall windows. They are bacchantes — the cheerful followers of Bacchus, the Roman god of wine. They laugh, they lean, they carry grapes. They fit a summer house built above a vineyard. The figures seem to hold up the roof, yet their faces show no effort at all. Frederick did not want heavy marble gods here. He wanted lightness.

Inside, the rooms follow a style called Rococo. Rococo was a playful eighteenth century fashion with curving lines, gold leaf and decoration taken from nature. At the centre stands the oval Marble Hall under the dome. Frederick held his famous dinners there. Guests talked about philosophy and literature, often in French. German was rarely heard at his table. The king preferred French culture all his life, and his library was full of French books.

The most famous guest was the French writer Voltaire. He spent several years at the Prussian court in the early 1750s. The friendship with Frederick was intense, but it ended badly, and Voltaire left in anger. Inside the palace there is a room called the Voltaire Room. Its walls carry carved and painted birds, flowers and fruit. Despite the name, it is not certain that Voltaire ever slept there. The name came later.

Music was just as important to the king. Frederick played the flute and wrote his own compositions. In the evenings, he gave small concerts in the music room with his court musicians. One of them was Carl Philipp Emanuel Bach, a son of Johann Sebastian Bach. Imagine the doors open in summer. The sound of a flute would drift out across the terraces and down toward the fountain.

Now walk to the eastern end of the upper terrace. You will find a flat stone slab, simple and almost hidden. This is the grave of Frederick the Great. He died at Sanssouci in 1786 and asked to be buried here, beside his beloved greyhounds. His successor ignored that wish. The body travelled from church to castle for two centuries. Only in 1991, after German reunification, did the king finally return to this terrace.

On the grave, you will often see potatoes. They are not litter. Frederick encouraged Prussian farmers to grow potatoes, which helped feed the country in hard times. Visitors now leave potatoes on his tomb as a thank you. Also look toward the old windmill near the palace. A popular legend says a stubborn miller refused to sell it and won his case against the king in court. Historians doubt the story — but Potsdam loves it.

Below the terraces lies the Great Fountain. Frederick dreamed of tall jets of water, but his engineers could not make them work. In his lifetime the fountains stayed mostly dry. Success came only in the nineteenth century, when a steam pumping station was built at the edge of the park. That pumping house was dressed up to look like a mosque. Look north, too, at the hill with artificial ruins. They hide a water reservoir.

Sanssouci is only the beginning. The park around it stretches far to the west, with the huge New Palace, the gilded Chinese House and many quiet paths. Together with other palaces in Potsdam and Berlin, it is a UNESCO World Heritage Site. But this small yellow house remains the heart of it all. Before you leave, stand at the foot of the steps and count them slowly. Then look up at the dome, at the vines, at that strange little comma... and take a moment without worries, just as the king intended.
