On an area of 1,400 m2, a steel maze was installed at the arts center C‑Mine in Genk (Belgium), to celebrate the 10th anniversary of the arts center which is located at the former coal mine of Winterslag.

It took almost one month to install this temporary construction which closed its doors at the end of September 2015.


The maze has a length of one kilometer and measures 37.5 x 37.5 m.

You enter and leave the maze through a single place in the shape of a canopy cut in the steel plates.

The plates made of Steel S235 have a length of 1.5 m as well as a width of 5 m and a thickness of 5 mm.

They were cut by using laser technology, then chamfered and painted so that the visitors can interact with the structure.

Structural Analysis

Particular attention was paid to the design of the deformations, the stresses and the stability under the effect of wind as well as to plate buckling.

Special technical solutions were developed for the welds, the ground fixation, the horizontal stiffening under the influence of the wind loads as well as for the local plate buckling.
