Cyril Lancelin unveils pyramid curbs in Grand Rapids
At the Return to the River festival in Grand Rapids, Cyril Lancelin – Town and Concrete introduces his latest large-scale inflatable installation, Pyramid Curbs. The vibrant, immersive structure transforms the urban landscape into a playground of color and geometry, inviting visitors to step inside a three-dimensional rainbow maze.
The artwork is composed of intertwined tubular forms that rise and curve into an abstract pyramid-like silhouette. Its surface is covered in a gradient of rainbow hues, producing a dazzling visual effect that shifts with light and perspective. From afar, Pyramid Curbs appears as a monumental bundle of neon-colored roots, while up close it becomes a walkable labyrinth where visitors can explore and lose themselves between the inflated walls.

integrating sculpture, architecture, and playground
True to French artist-architect Cyril Lancelin’s practice, the work blurs the boundaries between sculpture, architecture, and playground. Repetition and variation of geometric modules create a structure that is at once monumental and approachable. The installation celebrates collectivity and joy, encouraging people of all ages to engage physically and emotionally with the piece.
Return to the River provides the backdrop for this urban intervention, reconnecting Grand Rapids’ downtown with the waterfront through art, music, and public events. In this context, Pyramid Curbs acts as both a landmark and a social condenser, a meeting point where color, scale, and form merge to reimagine how public space can feel.
