Historic centre

San Lorenzo Cathedral developed from a medieval church associated with the Genoese community of Trapani, reflecting the city’s importance as a commercial and maritime centre. Standing close to Porta Oscura and the medieval walls, the church underwent substantial development during the fifteenth century and became a parish church serving the expanding city.

Its present appearance is largely the result of later transformations. The interior was substantially rebuilt around the beginning of the eighteenth century, while Giovanni Biagio Amico, the Trapanese priest and architect, subsequently played a major role in shaping the building. His work included the façade, begun in 1736, and the dome, together with interventions to the chapels and other parts of the church. The resulting architecture combines surviving earlier fabric with the strongly Baroque character that defines the cathedral today.

Further decoration was added in the early nineteenth century, including stucco work and painted figures of Patriarchs and Prophets commissioned by Monsignor Diego De Luca. The church’s institutional importance also continued to grow. When Pope Gregory XVI established the Diocese of Trapani in 1844, San Lorenzo became the cathedral and episcopal seat of the new diocese. It remains the principal cathedral church of Trapani and is dedicated to Saint Lawrence the Martyr.

Explore the development of San Lorenzo from a church associated with Trapani’s Genoese community to the city’s cathedral, including its Baroque transformation and the work of Giovanni Biagio Amico.


The Genoese church


Before becoming Trapani’s cathedral, San Lorenzo was associated with the Genoese community established in the city. Its medieval origins reflect the commercial connections that linked Trapani with other ports of the western Mediterranean and brought communities of merchants and seafarers to the city.


The church originally stood just outside the medieval wall circuit, close to Porta Oscura. Major construction or reorganisation took place during the early fifteenth century, traditionally associated with royal patronage during the Aragonese period. By the second half of the century San Lorenzo had acquired parish status, marking its development from a church associated with a particular community into an increasingly important institution within the religious life of Trapani.


The Baroque transformation


The Baroque appearance of San Lorenzo Cathedral developed through more than one phase. Giuseppe Maria Di Ferro recorded that the interior was largely reconstructed around the beginning of the eighteenth century under the parish priests Gaspare Vento and Giovanni Messina, following a design attributed to the Franciscan architect Padre Certo of Messina. Large windows were introduced to increase the amount of natural light within the church.


A later phase is associated with Giovanni Biagio Amico. The façade, begun in 1736, uses curved and recessed surfaces and superimposed architectural orders to create movement and depth. Its complex stone construction also demonstrates the geometric and stereotomic techniques that formed an important part of Amico’s architectural practice.


Amico was also responsible for the dome and contributed to the development of the chapels and other elements of the church. Together, these successive interventions gave the earlier building the predominantly Baroque architectural identity visible today.


Giovanni Biagio Amico


Giovanni Biagio Amico (1684–1754) combined his career as an architect with that of a Catholic priest. Born in Trapani, he was largely self-taught in architecture, developing his knowledge through the study of drawing, mathematics and architectural treatises as well as practical experience.


His connection with San Lorenzo was both architectural and ecclesiastical: Amico served as a priest of the church while contributing to its eighteenth-century transformation. His wider career included appointments as architect to the Senate of Trapani and engineer of the Royal Patrimony of the Kingdom of Sicily, alongside commissions for religious and civic buildings throughout western Sicily.


Amico also set out his architectural knowledge in L’Architetto pratico, published in two volumes in 1726 and 1750. His work at San Lorenzo therefore formed part of a broader practice combining architectural theory, engineering and the design of some of the most important Baroque buildings of eighteenth-century Trapani.


The historic interior


Giuseppe Maria Di Ferro’s 1825 description of San Lorenzo provides a record of its interior before later changes. He described walnut choir stalls enriched with carving and light gilding, as well as the decorative work commissioned by Monsignor Diego De Luca in 1801.


Among the paintings recorded by Di Ferro was a Saint George by the Trapanese painter Andrea Carreca, then located in the second chapel on the left. Di Ferro particularly admired the movement of the composition and the expressive treatment of its figures.


His account also describes Amico’s dome, whose hemispherical form departed from the pointed profiles associated with the earlier Gothic architectural tradition. These descriptions provide evidence for the appearance and artistic contents of San Lorenzo during the period immediately before it became Trapani’s cathedral.
