Historical and Artistic Context

Since the 19th century, Brussels has fostered a rich tradition of public art, transforming city spaces into open-air galleries that blend historical and contemporary aesthetics. Among the 272 monuments and 32 protected contemporary installations in Brussels, Capteurs De Ciel stands out as a hallmark of kinetic art.

Created by Pol Bury (1922–2005), a leading figure in kinetic sculpture, Capteurs De Ciel embodies the artist’s fascination with movement and reflection. The sculpture’s trio of vertical cylinders, each topped with a motorized, reflective sphere, interacts with sunlight and atmospheric conditions, creating an ever-evolving visual dialogue with the city. This dynamic quality not only animates the urban environment but also echoes Brussels’ multicultural identity and spirit of innovation.

Structural Composition and Technical Description

Cylindrical Elements

The sculpture consists of three vertical stainless steel cylinders, each with a 75 cm (29.5 inches) diameter but varying in height:

First cylinder: 3.10 meters (10.17 feet)
Second cylinder: 3.35 meters (10.99 feet)
Third cylinder: 3.60 meters (11.81 feet)

This staggered arrangement creates a rhythmic, upward gesture, reminiscent of fingers reaching for the sky (Cirkwi, La Libre Belgique).

Spherical Components and Kinetic Mechanism

Atop each cylinder sits a highly polished, motorized stainless steel sphere. These spheres rotate slowly (about one revolution per minute), powered by discreet 40-watt electric motors housed within the structure. The smooth, silent motion and mirror finish create an engaging kinetic experience that changes with light, weather, and the surrounding cityscape (Cirkwi).

Materials and Durability

The use of corrosion-resistant, polished stainless steel ensures longevity and enhances the sculpture’s reflective qualities. The base is integrated into the landscape with reinforced concrete and paving stones for stability and visual harmony.
