About Alexander Calder
Paris keeps a Calder
When UNESCO built its Paris headquarters in the seventh arrondissement, it commissioned art from the leading modernists — Picasso, Miró, Moore — and from Calder, who had become an artist in the city three decades earlier. Spirale, installed in 1958, stands about ten metres tall: a fixed pylon carrying an upper spiral of blades that turn with the wind.
It remains Calder's permanent public work in Paris, a short walk from the École Militaire, with the Eiffel Tower — built by the engineers' Paris he loved — in view across the Champ de Mars.
Close reading
Reading the work, detail by detail
A grounded support carries an ascending chain of balanced elements. The photograph lets us compare its broad base, fine upper rods, and the distant Eiffel Tower.
1.The grounded base
The broad footprint gives the sculpture a firm visual foundation. Above it, the structure quickly narrows, making the upper assembly look especially light.
2.The pivot
The meeting of upright and diagonal is the transition from support to balance. This small junction helps explain how the large forms can extend so far on either side.
3.The low broad shape
Its broad surface gives the left end visual weight. The form also provides a strong counterpoint to the much smaller pieces climbing toward the right.
4.The ascending chain
Successive branches become thinner and more widely separated against the sky. The eye moves upward through their intervals, giving the still photograph a sense of gradual lift.
5.An edge-on blade
Seen nearly edge-on, the hanging piece becomes a fine line. It reminds us that a mobile's visible shapes depend on their angle at the moment of looking.
6.The distant tower
The tower offers another structure that narrows as it rises. Its distant lattice contrasts with Calder's flat, dark planes, while the two silhouettes share the open sky.

Frequently asked questions
What is Spirale?
A monumental standing mobile Alexander Calder made for the UNESCO headquarters in Paris, installed in 1958 — a fixed steel pylon carrying a wind-turned spiral of blades, about ten metres tall.
Where exactly is Spirale?
At UNESCO's headquarters on the place de Fontenoy in the seventh arrondissement of Paris, near the École Militaire and the Champ de Mars.
Why did UNESCO commission Calder?
Its new 1958 headquarters was decorated by the leading modern artists — Picasso, Miró and Henry Moore among them — and Calder, formed as an artist in 1920s Paris, made the kinetic contribution.
Does Spirale move?
Yes. The lower structure is fixed, and the upper spiral of paddle-shaped blades rotates with the wind — a mobile at architectural scale.
Can visitors see Spirale?
It stands in UNESCO's grounds; sightlines from the surrounding streets show it, and UNESCO's visits and open days allow a closer look.
