Belvédère

City of Rennes

2020

Anchored in the middle of the Vilaine river, nearly six meters from the shore, the kiosk acts as a new lighthouse, poetically punctuating the boundary between solid ground and moving water. A footbridge leads from the quay, inviting pedestrians to reach the platform, which rests firmly on a foundation; above, a tubular mesh encircles visitors, defining an octagonal volume 11.30 meters high. 

‍

The structure is composed of eight stainless steel masts, hand-polished and linked together by a series of horizontal crossbeams. 

‍

This installation is characterized by a meticulous focus on the artisanal and industrial techniques employed. Tubes typically reserved for the petrochemical industry were used and hand-finished, while wind-driven moving parts and custom-made lighting fixtures, developed and manufactured in the region, soften and punctuate the geometry. Distributed throughout the structure, these wind-responsive elements lend the installation spatial richness and technical refinement. By interacting with natural conditions, they create rhythm and variation—a symphony in space that evolves with its environment according to the breeze. The elegant, slender lines of the masts form a composition that contrasts with the interplay of light and the movement of the structural elements. Extending from the quays, the footbridge allows for a suspended stroll, offering visitors a new perspective on the river while they experience these changing natural conditions.

Movement, light, and reflections evolve with the wind, giving the structure a rhythm dictated by its environment.
