I went to Lyon to visit a close friend in October and on a chilly October Saturday afternoon, I visited the Confluence centre. I was struck by it’s bold walls contrasting with curves and sharp edges, almost as a symbol of the fluid nature that cement moves in, in order to solidify. With triangular metal panelling tiled in a jagged mosaic up the walls, I felt impelled to look back at the building every step I took, as it continually appeared changed in a new light, with new curves or new edges. With rivers side by side, joining at the building’s tip, it felt a lot like being in a submarine that’s emerging out of the water. Confluence is quite a remarkable architectural monument in Lyon, bringing together all walks of life to enjoy, observe and play with its beauty.
