As previously mentioned, the parish of Parish of San Lorenzo has undergone numerous modifications over the centuries to reach its current appearance. From the façade, visible from the churchyard, one can see the statue of San Lorenzo flanked by Faith and Hope; a simple front, similar to those of nearby churches, that invites one to discover the richness stored inside.

The church houses seven altars: to the left the Our Lady of Sorrows and Our Lady of Mount Carmel; followed by the one dedicated to Archangel Michael, once titled St. Stephen. The main altar, in honor of San Lorenzo, recalls in style that of the Church of Our Lady of Mercy (1667). In the niche is the wooden statue of the Saint from the seventeenth century, brought in procession on August 10; above the altar is a crucifix attributed to Anton Maria Maragliano.

To the right are the altar of Our Lady of the Rosary, with fifteen panels of the mysteries, and those of the Holy Trinity and St. Anthony; in the corner is the marble baptismal font.

The frescoes are of particular significance, including the Martyrdom of San Lorenzo, the Annunciation, and San Lorenzo in Glory (late seventeenth century). The vaults feature the virtues — Fortitude, Justice, Chastity, and Humility — and the four evangelists.

The pulpit, probably from the fifteenth century, is the oldest and most precious work: attributed to the stonemasons of Cenova (now a hamlet of Rezzo), it depicts the Crucifix, Our Lady, and San Lorenzo and bears the inscription “Oleum effusum nomen tuum”, a reference to Christian symbols and the local olive oil tradition.
