"La Concha" is the name of the urban installation developed in the summer of 2020 by the Sebastián Arquitectos team located in the La Concha bay in the city of San Sebastian, on the coast of the Bay of Biscay.

The effectuated project consists of a dynamic installation that is achieved through the use of long-range laser projectors, which sweep the 1,200 m distance between the Island of Santa Clara and the beach of San Sebastian.
Born from a lighthouse, a visual repertoire of dynamic effects of the light itself unfolds. The various suspended moisture filters generate diverse and interesting effects, as well as the diffraction of light in a chromatic prism, bathing the sand and casting a multi-colored rainbow against the wall of the historic seafront.

With this installation by Sebastián Arquitectos, it is proposed the construction of an intervention that enhances and allows updating, in ephemeral terms, the image of the city through the symbiosis between art and nature.
 

Description of project by Sebastián Arquitectos

How to update the image of a city, its symbol more defined and clear. Historically, the relationship between art and nature has produced various types of conversation depending on the degree of intervention developed, bringing us suggestive, abrupt, violent, friendly, enriching, or surprising dialogues.

"La Concha" is proposed from the terms of the ephemeral, of the construction of an event that, within the licenses granted by its completely reversible and instantaneous character, adorns and dresses for the occasion of the already beautiful delivery of the sea to the city ​​in this natural basin.

Artificial light thus becomes the most powerful tool for painting the spokes that redraw this gigantic shell at night in San Sebastian.

However, the tremendous visual impact of this urban mural is instantly blurred as if nothing had ever happened.

This is the illusion of light, the magic of the event.

San Sebastián is a great urban theater, the biggest stage we can imagine.

La Concha is an installation carried out in the summer of 2020 with long-range laser projectors that sweep the distance of 1,200 m between the Island of Santa Clara and the beach, and that will grow over the next few years to become an installation dynamic, accompanied by an audiovisual show with a territorial dimension, which covers the entire bay and allows different perceptions either from the beach, the promenade and the Igueldo and Urgull mountains.

In the distance from the high points of the city, the work is perceived as a large shell. But it is from the same plane of the water and from the beach, where the rays acquire their own and extraordinary dimension. Born from a large lighthouse, they display a whole visual repertoire of dynamic effects of the light itself in their play with the atmospheric conditions of the beach, with the mist, steam, the movement of the waves, and the sand. The various suspended moisture filters generate dynamic shadows, vaporous clouds of color, and the diffraction of light in a chromatic prism, bathing the sand and striking like a multi-colored rainbow against the wall of the historic boulevard.
