“Walking, Listening and Recomposing Everyday Sounds of Esch” comprise three routes to discover the art of sound walking, exploring a specific topic characteristic for Esch's identity and development: “City Stories for the Ear” unearths the garden city's acoustic legacy and introduces visitors to contemporary strategies for making cities greener. “Memories of the Blue Noise” draws attention to the broken and obscured noises and sounds of the river Alzette, which flows underground the city squares. “Fading Thunders of Belval” immerses visitors in immense dimensions of steel structures contrasting with expansive brick walls, monstrous cranes, and labyrinths of giant pipes that shape and direct today's everyday sounds.
