Palazzo delle Poste is an early 20th-century post-office building in Trapani, Sicily. Designed by the architect Francesco La Grassa, it was constructed between 1924 and 1927 and remains a prominent example of the Liberty style in the cityâÂÂs civic architecture. The building occupies a full urban block with a trapezoidal plan and defines the southern frontage of the former Piazza Cavour (today part of the city centre).
The Palazzo was commissioned in the early 1920s by the Sicilian division of the Provveditorato alle Opere Pubbliche. The foundation stone was laid on 10 July 1923, during a ceremony attended by the Minister of Posts and Telegraphs, Giovanni Antonio Colonna di Cesarò. Works began in 1924 and were completed in 1927, the date visible on the façade. Postal services were subsequently transferred from the former offices in the ex-church and convent of San Rocco in Via Turretta, now the Museum of Contemporary Art San Rocco.
In July 2022 the principal façade was restored in a conservation programme conducted by Poste Italiane in collaboration with the regional heritage authorities, returning the decoration to its original Liberty-era appearance and renewing deteriorated external elements.
The building is constructed around a trapezoidal block and rises three storeys above ground, with façades forming a monumental urban presence. The main south-facing elevation is composed of a symmetrical arrangement of recessed pointed arches (sesto acuto) framed by lesene (pilaster strips), alternating with vertical pilaster strips â a pattern that gives the façade rhythmic unity while subtly referencing Islamic-inspired arch forms, but expressed through a modern Liberty vocabulary.
Decorative motifs throughout the exterior and interior are inspired by the buildingâÂÂs function: stylized postal- and telecommunication-themed elements such as envelopes, telegraph insulators, cables, and Morse-code symbols appear in sculptural panels, ironwork, grilles and interior furnishings. In contrast to some earlier Liberty works, floral ornamentation is limited â instead, La Grassa favoured a disciplined, functional aesthetic, with surfaces, structural rhythm, and symbolic decoration forming a cohesive architectural statement.
Inside, the public hall is covered by a large stained-glass canopy (velario) realised by the glassmaker Pietro Bevilacqua â a collaborator of Ernesto Basile â whose colourful motifs echo the external decoration. A monumental stone-block "scala alla trapanese" staircase with exposed cantilevered treads leads to upper floors, a structural-stylistic hallmark of La GrassaâÂÂs regional work. The windows, metalwork, and interior décor combine Liberty-era stylistic elegance with the robust functional needs of a modern postal facility. The building thus represents one of the most important civic-architecture examples of early 20th-century Trapani.
