Neue Nationalgalerie

Stand still for a moment on the wide granite terrace. The stone is pale and cool, and it runs out in every direction like a frozen lake. Above you, a black steel roof floats with almost nothing beneath it. Through the glass walls, you can see straight through the building to the trees and the traffic beyond. The building feels less like a box and more like a pause in the city.

This is the Neue Nationalgalerie, the New National Gallery. It sits at the Kulturforum, a cluster of cultural buildings near Potsdamer Platz. It opened in 1968, and it holds one of Germany's most important collections of twentieth-century art. But for many visitors, the building matters as much as the paintings inside. It is often called a temple of light and glass, and once you stand here, the phrase makes sense.

The architect was Ludwig Mies van der Rohe. Before the war, he led the Bauhaus, the influential German school of art and design. The Nazis forced the school to close, and Mies left for the United States in the late 1930s. In Chicago he became one of the founders of modern architecture. This gallery brought him back to Berlin near the very end of his life. It was the last building he completed, and his only major work in post-war Germany.

Look up at that roof again. It is a single square plate of steel, about sixty-five metres on each side. Here is the first surprise. The roof was not built piece by piece in the air. Workers assembled it on the ground. Then, in 1967, hydraulic jacks lifted the whole thing in one slow operation, and it settled onto its columns. Berliners gathered to watch the steel rise.

Now count the columns. There are only eight, two on each side, set back from the corners. Each one has a cross-shaped profile, and each one narrows slightly toward the top. Nothing touches the corners at all. That is why the roof seems to hover. Mies often said that less is more, and here you can see the idea in practice. The structure carries the weight, and the walls do almost nothing except keep out the weather.

The second surprise is that most of the museum is under your feet. The glass hall upstairs is one open room with no fixed walls. It works best for large sculptures, installations and special exhibitions. The permanent collection lives in the stone podium below, in calmer galleries lit by more controlled light. So the building has two moods. Upstairs is air and openness. Downstairs is concentration and quiet.

The design has an unusual history. Mies had developed a similar idea earlier, for an office building in Cuba that was never built. He refined the concept for other projects, and Berlin finally gave it a home. Some critics at the time found the glass hall impractical for hanging paintings. Daylight, after all, can be hard on canvas. Mies accepted that trade-off. He wanted a universal space, a room that could change with every exhibition.

The collection below covers art from the early twentieth century through the post-war decades. You can meet the German Expressionists here, artists such as Ernst Ludwig Kirchner, who painted the restless streets of early Berlin. There are works by Otto Dix and George Grosz, who looked hard at the city after the First World War. Max Beckmann is here too. Many of these artists were attacked by the Nazis as degenerate, and some of their works were removed from German museums. Seeing them here, in this building, carries extra weight.

The gallery also holds important post-war art. One story stays with many visitors. In 1982, a man attacked a large painting by the American artist Barnett Newman. It was one of his works called Who's Afraid of Red, Yellow and Blue. The incident became part of a long debate about abstract art and why it provokes such strong reactions. Today, the collection's displays rotate, so what you see may change from one visit to the next.

By the early 2010s, the building needed serious care. The glass cracked, the steel had corroded, and the technical systems were old. The museum closed at the end of 2015 for a full restoration, led by the British architect David Chipperfield. His team took the building apart down to its structure. They catalogued, repaired and returned tens of thousands of original parts. The goal was to change as little as possible. The gallery reopened in 2021, looking almost exactly as Mies intended.

That restoration is easy to miss, and that is the point. Notice the original furniture in the glass hall, the low leather chairs and the simple cabinets. Notice the stone floor, which continues from the outside terrace into the interior without a break. Inside and outside use the same material. The building wants you to forget where the street ends and the museum begins.

Before you leave, walk down to the sculpture garden at the back of the podium. It is enclosed by stone walls, and it holds modern sculptures among trees and still water. The sound of traffic fades here. Then look around at the neighbours. The small brick Saint Matthew's Church stands right beside the gallery. Across the way, the golden, tent-like Philharmonie, by Hans Scharoun, offers a completely different idea of modern building. Mies worked in straight lines. Scharoun worked in curves.

That contrast is the story of this whole area. After the war and the building of the Berlin Wall, this part of West Berlin was close to the border and almost empty. The Kulturforum was an attempt to build a new cultural centre in that space. Today, with Potsdamer Platz rebuilt around it, the gallery no longer stands at the edge of anything. It sits at the heart of a reunited city.

So take one last look as you walk away. Turn around at the bottom of the steps. Watch how the glass catches the sky, and how the dark roof draws a clean line against the clouds. Late in the day, the lights inside come on, and the whole hall glows like a lantern. It is a simple shape. Eight columns, one roof, a wall of glass... and somehow, it is enough.
