In the heart of the Brenta Valley, just a few kilometres from the Luce&Light headquarters, the Oliero Caves are home to some of the largest karstic springs in Europe. It is a place where nature has been sculpting stone for millennia, creating majestic caverns, underground lakes and hidden landscapes of rare beauty. They are also a cultural and scientific treasure that tells the story of karst phenomena, exploration, and human occupation going back thousands of years.

On 8 October 2024, the site was hit by an exceptional flood event: the park, museums and visitor facilities were submerged by mud and debris, and the entire complex was severely damaged. The devastation also deeply affected the local community, which responded with extraordinary collective energy to bring the site back to life.

Committed to sustainability since its inception, L&L Luce&Light played a significant role in this process of renewal by contributing what it knows best: light. The lighting design, curated by lighting designer Chiara Carucci (Noctua) and developed in close collaboration with technicians, speleologists and researchers, had a twofold objective: to preserve the identity and delicate balance of the natural environment while enhancing the visitor experience through precise, discreet and sustainable lighting. This was also an opportunity to further promote the Oliero Caves as a place of discovery, education and awareness about underground water ecosystems.

The work carried out at the Oliero Caves is much more than a simple lighting project: it is an act of care and respect for a fragile and precious natural heritage. The lighting fixtures, donated by Luce&Light as a token of its commitment to the local community, were customized to integrate seamlessly into the site’s unique context.

The choice of Ginko 1.0 and Spot 1.0 projectors – with bodies and brackets made entirely of stainless steel and equipped with snoots to conceal the light source – made it possible to direct the light into the rock crevices, accentuating their texture and tonal variations through the use of different optics. Some fixtures were also fitted with customized elliptical filters, shaping the light to follow the lines of the geological stratifications. Warm 3000K lighting was used throughout most of the project to envelop the spaces in a natural and welcoming atmosphere.

At the base of the rocky vaults, Lyss mini 1.0 fixtures with 8°x160° optics cast a grazing light along the walking surface without disturbing the underground ecosystem. Their targeted light guides visitors while leaving the upper walls in shadow and preserving their air of mystery. Along the main walkway, Intono B bollards in a corten finish ensure safety and visibility, harmonizing with the surroundings and lighting the path with a soft, warm 2700K glow.

Finally, in the perennial spring at the entrance, a Spot 1.0 AISI 316L fixture in stainless steel, designed for continuous immersion, illuminates the water from below, highlighting one of the site’s most atmospheric views.

“We are proud to support the Oliero Caves with this new narrative,” explains Carucci. “It is an example of how light and darkness can enter into dialogue with the environment and the community to protect and reveal a fragile but invaluable heritage.”

This project demonstrates that, when light is carefully calibrated and designed to interact with its context, it can become a powerful means of both enriching and preserving the places it illuminates.
