Two copper high-reliefs four metres wide, placed opposite each other (1977)

This piece is a beautiful example of the interaction between sculpture and architecture. These monumental wall sculptures represent the movement of birds in the sky, the symbol of freedom. “In the underground world of the metro, there is no trace of air, sun, trees nor of any of the natural environment of human beings. People only think about moving around quickly and of wallowing in their problems. For all those who are prisoners of this miserable routine, I tried to create a bird in full flight as a symbol of freedom”, explains Jean-Pierre Ghysels. The artist designed his project in a style that is completely abstract, fluid and purely sculptural. As is often the case in his works, here he also uses soft and simple shapes, alternating between massive elements and empty spaces, allowing a free play of light.
