Atomium, Heysel Exhibition Park, Brussels, Belgium

As a symbol of Expo 58, the image of the Atomium is known around the world. Since October 2004 this landmark building, originally planned to last only six months, has been undergoing renovation.

An aluminium and steel construction of 102m high, this landmark development is the dominant element on the plateau of the Heysel in Brussels. The design team have seen their creation last through decades and gain fame as Belgium's answer to the Eiffel Tower.

THE ATOMIUM'S NINE SPHERES

The building represents an iron crystal molecule, with each sphere symbolising individual atoms. The structure is also said to represent Belgium's nine provinces, and was designed to bring harmony between the French and Flemish-speaking areas of the country.

As the long-awaited modernisation nears an end, the existing skin has been replaced with stainless steel outside and galvanised steel on the inside. The contemporary look of the new pavilion gives an extra dimension to the Atomium.

At the foot of the structure, there will be an urban square, from which visitors can admire the Atomium at various angles. At different positions throughout the complex, visitors can make use of a broad choice of urban furniture, and consider the contrasts between the foot of the building, the esplanade and the splendid view from the site.

INSIDE THE SPHERES AND TUBES

The inner space of the Atomium passes continuously through the spheres and tubes. The design revolves around the ideas of emptying, opening, perceiving and experiencing. The Atomium will take visitors on a journey through its spheres, giving them an entirely new aesthetic experience.

A visit to the Atomium begins in the bottom sphere, with an exhibition dedicated entirely to Expo 58 and details of how the structure was first built. Next are the spheres for temporary exhibitions – including artwork, photographs and film screenings. After this, the visitors proceed to the central sphere. While waiting for the lift there, they can quench their thirst in its two bars.

In the upper sphere, the public can sample the restaurant menu and enjoy the splendid panorama, created by the new windows. While descending, the visitors' route continues into the children's sphere. This will be a gateway to a dream world, with an overnight dormitory for visiting schoolchildren, entirely furnished with water molecules.

Six of the Atomium's nine spheres are accessible, offering a journey of discovery and a diverse range of perspectives.
