A new lighthouse for Geneva harbour: the Ylliam project takes shape

It's not every day that a new lighthouse takes up residence on a body of water, let alone Lake Geneva. The construction of the Ylliam lighthouse marks a milestone in the development of the Société Nautique de Genève harbour. Designed by architects BUREAU, this architectural project completes the recent transformations of Geneva's lakefront, including the expansion of the harbour and the development of the Quai Gustave-Ador and the Eaux-Vives beach. Installed at the end of the north jetty, the lighthouse is intended both as a beacon of light and a symbol of the harbor's renewal.

An innovative, minimalist structure

The 21-metre-high Ylliam lighthouse adopts a light, modern design. Its metal structure is supported by thin cables that preserve the view of the harbour, while offering a distinctive presence day and night. Unlike the Pâquis lighthouse, it will not be possible to climb up to it, as its lantern will be mobile and lowered to facilitate maintenance. This technical approach makes the architecture even lighter and meets the landscape requirements of the harbour.

A project born of necessity

The idea for this lighthouse arose from a remark by a landscape architect highlighting the new pier's lack of visibility, particularly at night. The Société Nautique de Genève then launched an architectural competition, won by BUREAU, to propose an integrated and discreet solution. The aim was to provide a visual landmark without imposing a massive structure on the landscape.

Private funding and limited impact

The cost of the project is estimated at around 2 million Swiss francs, financed entirely by sponsors who wish to remain anonymous. To minimize its impact on the environment and landscape, the construction also includes reinforcement of the riprap at the end of the breakwater, improving visibility of the jetty even in daylight.

A new icon for the Port of Geneva

With the forthcoming commissioning of the Ylliam lighthouse, Geneva's harbour is getting a new lighting signature. This "micro-monument", as its designers call it, combines functionality and aesthetics, blending harmoniously into the Geneva skyline. Its installation reflects a commitment to modernization that respects the city's heritage, while meeting the needs of port users and navigation enthusiasts alike.
