Caeruleum Prism: A Cultural and Environmental Intervention
at Punta Bianca
The Caeruleum Prism proposal reimagines the historic Customs House
at Punta Bianca as a dual-purpose site that houses both cultural heritage
and natural beauty. Anchored in the dramatic Mediterranean
landscape, the design respectfully preserves the original building while
introducing a new architectural volume that supports both educational
and recreational experiences.
The proposal responds to the site’s dual appeal—its historical significance
and unspoiled natural environment—by establishing two distinct
yet interconnected circulation routes: one culturally oriented and the
other leisure-focused. This approach allows the site to cater to a wide
audience, including history enthusiasts, hikers, and birdwatchers.
The cultural route begins within the restored Customs House. The northern
section of the existing ground floor houses exhibitions dedicated to
the first two historical phases of the building. Visitors are then guided
into the new volume, where the third historical period is presented. This
space is strategically oriented to frame views of the sea and nearby rock
formations, enriching the exhibition experience. The route continues
to a transitional staircase, which separates the new and old structures
while physically connecting them. Ascending to the terrace level, visitors
enter the library containing archival material, and finally the projections
room, where curated audiovisual content deepens their understanding
of the site’s layered history.
In parallel, the recreational path begins with direct access to the groundfloor
gift shop and continues upward to the café. The café features both
indoor and outdoor terrace spaces, offering visitors opportunities for
rest and panoramic views. This flexible spatial arrangement ensures the
site serves both educational and leisure purposes, enhancing its appeal
and accessibility.
Architecturally, the intervention emphasizes contrast rather than mimicry.
The new rectangular volume, elevated on slender columns and
rotated to follow the site’s topography, integrates into the natural landscape
without compromising its character. The physical gap between
the old and new is articulated through the staircase, creating a symbolic
and spatial transition. Materials such as metal, glass, and tiles in a distinctive
blue (caeruleum) palette highlight circulation paths and signify
the new intervention, drawing inspiration from the surrounding sea and
sky.
The Caeruleum Prism respects the heritage of the Customs House while
introducing a contemporary layer that invites discovery and reflection.
Through sensitive design and a deep respect for context, it offers a renewed
public space that harmonizes cultural storytelling with environmental
appreciation.
