Specus Corallii is a contemporary interior designed in 2015âÂÂ2016 by Italian architect Antonino Cardillo for the pastoral hall known as the Sala Laurentina in Trapani, Sicily. The project gained international attention for its coral-coloured, grotto-like surfaces and its reinterpretation of the city's maritime and coral-working heritage.
The Sala Laurentina occupies the former Church of the Santissimo Sacramento, an oratory belonging to the Trapani Cathedral complex. The building was severely damaged during the Second World War and subsequently used for community initiatives, including assistance to newly arrived immigrants and cultural events.
After nearly twenty years of disuse, the Diocese of Trapani restored the structure and reopened it in 2016 as a multifunctional pastoral centre serving the parishes of San Lorenzo and San Pietro.
Cardillo was commissioned to redesign the hall as part of the diocesan restoration programme. The initiative was promoted by parish priest Gaspare Gruppuso, who emphasised the need to give new cultural and social purpose to the long-disused Sala Laurentina and to create a space capable of serving the wider community.
The project was conceived as a contemporary âÂÂspecusâÂÂ, or cave-like chamber, drawing on TrapaniâÂÂs long-standing relationship with the sea and its coral-working traditions.
International design media highlighted the projectâÂÂs distinctive materiality and its atmospheric reinterpretation of grotto architecture.
Specus Corallii transforms the oratory into a sculptural interior characterised by low arches, vaulted ceilings and a continuous, enveloping spatial sequence. Critics described the space as an evocation of refuge, memory and maritime mythology.
The interior is finished with a coral-pink mixture of calcarenite, sand and pozzolana, applied to create a rough, stratified texture reminiscent of natural coastal caves. The granular surfaces absorb and diffuse light, producing shifting tonal variations throughout the day.
Light entering through the existing windows accentuates the irregularities of the plaster, creating a chiaroscuro effect that contributes to the immersive, cavernous atmosphere.
Symbolic elements reinforce the theme of journey and protection. A wooden inlay shaped like a moored boat marks the centre of the floor, while the sequence of arches at the entrance evokes the rhythm of waves. Scholars have interpreted the interior as a contemporary meditation on memory, myth and the sacred.
Specus Corallii received international coverage in architectural and design media, including Dezeen, Casabella and Mondo*Arc India. The project was also featured in travel and cultural publications, such as the DuMont guide to Sicily and Corriere della Sera â Living, which emphasised its atmospheric qualities and its role in the revitalisation of the cathedral complex.
