The WIR sculpture, designed by Oskar Zięta, stands at the very centre of Galeria Północna in Warsaw. It’s the tallest sculpture in Warsaw and the first manifesto of FiDU technology made on such a scale. Its unique, steel form is a fusion of contemporary art with architecture and parametric design.

…the tallest sculpture in Warsaw and the first manifesto of FiDU technology made on such a scale.


Galeria Północna opened in 2017 in Białołęka, Warsaw. It’s the main shopping centre for the residents of north-east Warsaw, and in the future may become a beacon for the entire northern metro area. The modern form of Galeria Północna is, to a great extent, covered with glass,

with grass and trees growing on its roof. The WIR sculpture is inspired by natural forms, fits with the visual assumptions of the shopping centre and enriches it with its own technological elements. The central location of the sculpture also makes it visible from all the floors.

Activation of human traffic on the upper floors

The WIR sculpture will bring Galeria Północna out of the conventions of regular shopping centres. Many visitors will come to see this unique piece of art, which stands out not only aesthetically but also for its construction and technology. It will make

Galeria Północna a prestigious spot for meetings and entertainment. The irregular structure of the sculpture should  also encourage visitors to make frequent changes of observation point, hence boosting visits to the centre’s higher floors.



The WIR sculpture was inspired by nature. It’s five wavy, intertwining profiles curl around it like streams of water. Its form references natural whirls, and its main characteristics – variability. Lean, tampering profiles give the sculpture a subtle, delicate appearance, despite its true enormity.

The sun, shining through the ceiling, reflects beautifully off its myriad surfaces. At the first design stage of the sculpture, we needed to establish what parameters were needed to generate the form. We then created custom software to allow modification of the design using Bezier curves.


Parametric design

The shape of the WIR sculpture was created using parametric design, with several generations of varied profile arrangements were created before selecting the final form. Parametrics also helped us effectively control the design process and prototype every stage.

These 3D-printed prototypes allowed for quick visualisation of our work. We could physically check the functionality and stability of the designed forms, as well as judge them from different angles.



For us, creating the tallest FiDU sculpture in the world was a project on an unprecedented scale. In order to even begin the technologically advanced process, we needed to find an assembly room large enough, further adjust its space,

prepare proper workbenches, import materials from Italy and gather together the production tools. Every stage of the prep work was supervised by a team of specialists who, step by step, worked together to create a new showcase for FiDU.


The Venetian steel used in the sculpture is a very delicate material, and required extremely careful handling during transport. Each profile piece was tightly packed to avoid any scratching. The secured pieces were then loaded onto lorries using a hoist and a forklift. Then, marked ‘Blown with love’, they left

on an overnight journey from Zielona Góra to Warsaw. Each profile piece had to be taken down from the lorry, then brought to a vertical position using a crane and hoist, and lowered into the shopping centre through the roof (the heaviest of the pieces weighed 900 kg).

A drop-shaped cap was designed for each piece of the WIR. These had to be welded to the profile pieces for secure anchoring to the ground. Since objects made in FiDU technology are characterised by irregular shapes, every profile piece has its own different cap. Mounting points for the WIR were lain in before the site was closed off by the roof. Once they had been lowered into place through the roof,

the pieces were fixed to round plates that had earlier been positioned by surveyors. These anchors ,protruding from the concrete, had to be precisely matched with the bolts on the profiles’ end caps. Finally, this lengthy, strenuous process was successfully completed, and the WIR sculpture stood in its destined location.

The WIR sculpture

is 22m high,

consists of five

intertwining profiles

and provides a totally

different look,

depending on the height

and point of observation.

Its unique steel form

is a fusion of

contemporary art

with architecture and parametric design.

The WIR sculpture

will bring

Galeria Północna out of the conventions

of regular shopping centres.
